Black Sabbath

Butler, Gillan and Bevan parted ways in 1984, leading to a hiatus and Iommi and Nicholls assembling a new version of Black Sabbath the following year. For the next twelve years, the band endured many personnel changes that included vocalists Glenn Hughes, Ray Gillen and Tony Martin, the latter's tenure was the longest, joining in 1987 and recording three albums before his initial departure in 1991: The Eternal Idol (1987), Headless Cross (1989), and Tyr (1990). That same year, Tony Iommi and Geoff Nicholls reunited with Geezer Butler, Ronnie James Dio and Vinny Appice to record Dehumanizer (1992), though Dio and Appice both departed by the end of 1992. Martin returned for two more studio albums, Cross Purposes (1994) and Forbidden (1995), and one live album, Cross Purposes Live, before the band went on a one-year hiatus.

The original line-up of Tony Iommi, Ozzy Osbourne, Geezer Butler and Bill Ward reunited in 1997, releasing a live album, Reunion, and touring sporadically until 2005, most of which saw Black Sabbath headline Ozzy Osbourne's annual festival tour Ozzfest. The band went on hiatus in 2006 when the Mob Rules line-up reunited as Heaven & Hell, touring during the late 2000s and releasing its sole studio album, The Devil You Know, in 2009 before disbanding after Dio's death. The original line-up reunited again in 2011, though Ward departed prior to the recording of their final studio album and 19th overall, 13 (2013). To conclude their farewell tour, Black Sabbath played its last concert for eight years in their home city in 2017. Occasional partial reunions have occurred, most notably when Osbourne and Iommi performed at the closing ceremony of the 2022 Commonwealth Games in Birmingham. The original line-up will reunite for a final show for the band and Osbourne as a solo musician, titled Back to the Beginning, at Villa Park on July 5, 2025.

Black Sabbath have sold over 70 million records as of 2013, making them one of the most commercially successful heavy metal bands. The band have been referred to as the "unholy trinity of British hard rock and heavy metal in the early to mid-seventies", along with Deep Purple and Led Zeppelin. Black Sabbath were ranked by MTV as the "Greatest Metal Band of All Time" and placed second on VH1's "100 Greatest Artists of Hard Rock" list. Rolling Stone magazine ranked them 85 on its "100 Greatest Artists of All Time". They were inducted into the UK Music Hall of Fame in 2005 and Rock and Roll Hall of Fame in 2006. They have won two Grammy Awards for Best Metal Performance, and received a Grammy Lifetime Achievement Award.

Following the break-up of their previous band, Mythology, in 1968, guitarist Tony Iommi and drummer Bill Ward sought to form a heavy Blues rock band in Aston, Birmingham. They enlisted bassist Geezer Butler and vocalist Ozzy Osbourne, who had played together in a band called Rare Breed, Osbourne having placed an advertisement in a local music shop: "OZZY ZIG Needs Gig – has own PA".

The new group was initially named the Polka Tulk Blues Band, the name taken either from a brand of talcum powder or an Indian/Pakistani clothing shop; the exact origin is confused. The Polka Tulk Blues Band included slide guitarist Jimmy Phillips, a childhood friend of Osbourne's, and saxophonist Alan "Aker" Clarke. After shortening the name to Polka Tulk, the band again changed their name to Earth (which Osbourne hated),

and continued as a four-piece without Phillips and Clarke. Iommi became concerned that Phillips and Clarke lacked the necessary dedication and were not taking the band seriously. Rather than asking them to leave, they instead decided to break up and then quietly reformed the band as a four-piece. While the band was performing under the Earth moniker, they recorded several demos written by Norman Haines such as "The Rebel", "When I Came Down" and "Song for Jim", the latter of which being a reference to Jim Simpson, who was a manager for the bands Bakerloo Blues Line  and Tea & Symphony, as well as the trumpet player for the group Locomotive. Simpson had recently started a new club named Henry's Blueshouse at The Crown Hotel in Birmingham and offered to let Earth play there after they agreed to waive the usual support band fee in return for free T-shirts. The audience response was positive and Simpson agreed to manage Earth.

In December 1968, Tony Iommi abruptly left Earth to join Jethro Tull. Although his stint with the band would be short-lived, Tony Iommi made an appearance with Jethro Tull on The Rolling Stones Rock and Roll Circus TV show. Unsatisfied with the direction of Jethro Tull, Iommi returned to Earth by the end of the month. "It just wasn't right, so I left", Iommi said. "At first I thought Tull were great, but I didn't much go for having a leader in the band, which was Ian Anderson's way. When I came back from Tull, I came back with a new attitude altogether. They taught me that to get on, you got to work for it."

While playing shows in England in 1969, the band discovered they were being mistaken for another English group named Earth, so they decided to change their name again (this name change would give rise to the well-known debate about the alleged aesthetic influence of Coven, which the British band always denied). A cinema across the street from the band's rehearsal room was showing the 1963 Italian horror film Black Sabbath, starring Boris Karloff and directed by Mario Bava. While watching people line up to see the film, Geezer Butler noted that it was "strange that people spend so much money to see scary movies". Following that, Osbourne and Butler wrote the lyrics for a song called "Black Sabbath", which was inspired by the work of horror and adventure-story writer Dennis Wheatley, along with a vision that Geezer Butler had of a black silhouetted figure standing at the foot of his bed. Making use of the musical tritone, also known as "the Devil's Interval", the song's ominous sound and dark lyrics pushed the band in a darker direction, a stark contrast to the popular music of the late 1960s, which was dominated by flower power, folk music and hippie culture. Judas Priest frontman Rob Halford has called the track "probably the most evil song ever written". Inspired by the new sound, the band changed their name to Black Sabbath in August 1969, and made the decision to focus on writing similar material in an attempt to create the musical equivalent of horror films.

The band's first show as Black Sabbath took place on August 30, 1969 in Workington, England. They were signed to Philips Records in November 1969. They recorded their first single, "Evil Woman" (a cover of a song by the band Crow), at Trident Studios. "Evil Woman" was released on January 9, 1970 through Philips subsidiary Fontana Records. Later releases were handled by Philips' newly formed progressive rock label, Vertigo Records. "Evil Woman" failed to chart.

The band were afforded two days of studio time in November 1969 to record their debut album with producer Rodger Bain. Tony Iommi recalls recording live: "We thought, 'We have two days to do it, and one of the days is mixing.' So we played live. Ozzy was singing at the same time; we just put him in a separate booth and off we went. We never had a second run of most of the stuff".

On November 11, 1969 Black Sabbath recorded a four-song session for John Peel's Top Gear radio show. The four songs were "Black Sabbath", "N.I.B.", "Behind the Wall of Sleep" and "Sleeping Village". Broadcast on November 29, 1969, this gave them their first exposure to a UK wide audience.

Their debut album Black Sabbath was released on Friday the 13th, February 1970, and reached number eight in the UK Albums Chart. Following its U.S. and Canadian release in May 1970 by Warner Bros. Records, the album reached number 23 on the Billboard 200, where it remained for over a year. The album was given negative reviews by many critics. Lester Bangs dismissed it in a Rolling Stone review as "discordant jams with bass and guitar reeling like velocitised speedfreaks all over each other's musical perimeters, yet never quite finding synch". It sold in substantial numbers despite being panned, giving the band their first mainstream exposure. It has since been certified Platinum in both U.S. by the Recording Industry Association of America (RIAA) and in the UK by British Phonographic Industry  (BPI), and is now generally accepted as the first Heavy metal album.

The band returned to the studio in June 1970, just four months after Black Sabbath was released. The new album was initially set to be named War Pigs after the song "War Pigs", which was critical of the Vietnam War; however, Warner changed the title of the album to Paranoid. The album's lead single, "Paranoid", was written in the studio at the last minute. Bill Ward explains: "We didn't have enough songs for the album, and Tony just played the [Paranoid] guitar lick and that was it. It took twenty, twenty-five minutes from top to bottom."

The single was released in September 1970 and reached number four on the UK Singles Chart, remaining Black Sabbath's only top 10 hit. The album followed in the UK in October 1970, where, pushed by the success of the "Paranoid" single, it reached number one on the UK Albums Chart. The U.S. release was held off until January 1971, as the Black Sabbath album was still on the chart at the time of Paranoid's UK release. The album reached No. 12 in the U.S. in March 1971, and would go on to sell four million copies in the U.S. with virtually no radio airplay. Like Black Sabbath, the album was panned by rock critics of the era, but modern-day reviewers such as AllMusic's Steve Huey cite Paranoid  as,

"one of the greatest and most influential heavy metal albums of all time", which "defined the sound and style of heavy metal more than any other record in rock history". The album was ranked at number 131 on Rolling Stone magazine's list of The 500 Greatest Albums of All Time. Paranoid's chart success allowed the band to tour the U.S. for the first time – their first U.S. show was at a club called Ungano's at 210 West 70th Street in New York City – and spawned the release of the album's second single, "Iron Man". Although the single failed to reach the top 40, it remains one of Black Sabbath's most popular songs, as well as the band's highest-charting U.S. single until 1998's "Psycho Man".

In February 1971, after a one-off performance at the Myponga Pop Festival in Australia, Black Sabbath returned to the studio to begin work on their third album. Following the chart success of Paranoid, the band were afforded more studio time, along with a "briefcase full of cash" to buy drugs. "We were getting into coke, big time", Bill Ward explained. "Uppers, downers, Quaaludes, whatever you like. It got to the stage where you come up with ideas and forget them, because you were just so out of it."

Production completed in April 1971, and in July the band released Master of Reality, just six months after the U.S. release of Paranoid. The album reached the top 10 in the U.S. and the United Kingdom, and was certified Gold in less than two months, eventually receiving Platinum certification in the 1980s and Double Platinum in the early 21st century. It contained Sabbath's first acoustic songs, alongside fan favourites such as "Children of the Grave" and "Sweet Leaf". Critical response of the era was generally unfavourable, with Lester Bangs delivering an ambivalent review of Master of Reality in Rolling Stone, describing the closing "Children of the Grave" as "naïve, simplistic, repetitive, absolute doggerel – but in the tradition [of rock 'n' roll] ... The only criterion is excitement,

and Black Sabbath's got it". (In 2003, Rolling Stone would place the album at number 300 on their 500 Greatest Albums of All Time list.)

Following the Master of Reality world tour in 1972, the band took their first break in three years. As Bill Ward explained: "The band started to become very fatigued and very tired. We'd been on the road non-stop, year in and year out, constantly touring and recording. I think Master of Reality was kind of like the end of an era, the first three albums, and we decided to take our time with the next album."

In June 1972, the band reconvened in Los Angeles to begin work on their next album at the Record Plant. With more time in the studio, the album saw the band experimenting with new textures, such as strings, piano, orchestration and multi-part songs. Recording was plagued with problems, many as a result of substance abuse issues. Struggling to record the song "Cornucopia" after "sitting in the middle of the room, just doing drugs", Bill Ward was nearly fired. "I hated the song, there were some patterns that were just ... horrible," the drummer said.

"I nailed it in the end, but the reaction I got was the cold shoulder from everybody. It was like, 'Well, just go home; you're not being of any use right now.' I felt like I'd blown it, I was about to get fired". Geezer Butler thought that the end product "was very badly produced, as far as I was concerned. Our then-manager insisted on producing it, so he could claim production costs". The album was originally titled Snowblind after the song of the same name, which deals with cocaine abuse. The record company changed the title at the last minute to Black Sabbath Vol. 4. Bill Ward observed,

"There was no Volume 1, 2 or 3, so it's a pretty stupid title, really". Vol. 4 was released in September 1972, and while critics were dismissive, it achieved Gold status in less than a month, and was the band's fourth consecutive release to sell a million in the U.S. "Tomorrow's Dream" was released as a single – the band's first since "Paranoid" – but failed to chart.

Following an extensive tour of the U.S., in 1973 the band travelled again to Australia, followed by a tour for the first time to New Zealand, before moving onto mainland Europe. "The band were definitely in their heyday", recalled Ward, "in the sense that nobody had burnt out quite yet".

Following the Vol. 4 world tour, Black Sabbath returned to Los Angeles to begin work on their next release. Pleased with the Vol. 4 album, the band sought to recreate the recording atmosphere, and returned to the Record Plant studio in Los Angeles. With new musical innovations of the era, the band were surprised to find that the room they had used previously at the Record Plant was replaced by a "giant synthesiser".

The band rented a house in Bel Air and began writing in the summer of 1973, but in part because of substance issues and fatigue, they were unable to complete any songs. "Ideas weren't coming out the way they were on Vol. 4, and we really got discontent", Tony Iommi said. "Everybody was sitting there waiting for me to come up with something. I just couldn't think of anything. And if I didn't come up with anything, nobody would do anything". After a month in Los Angeles with no results, the band opted to return to England. They rented Clearwell Castle in The Forest of Dean. "We rehearsed in the dungeons and it was really creepy, but it had some atmosphere, it conjured up things and stuff started coming out again".

While working in the dungeon, Tony Iommi stumbled onto the main riff of "Sabbath Bloody Sabbath", which set the tone for the new material. Recorded at Morgan Studios in London by Mike Butcher and building off the stylistic changes introduced on Vol. 4, new songs incorporated synthesisers, strings and complex arrangements. Yes  keyboardist Rick Wakeman was brought in as a session player, appearing on "Sabbra Cadabra".

In November 1973, Black Sabbath began to receive positive reviews in the mainstream press after the release of Sabbath Bloody Sabbath, with Gordon Fletcher of Rolling Stone calling the album "an extraordinarily gripping affair" and "nothing less than a complete success". Later reviewers such as AllMusic's Eduardo Rivadavia cite the album as a "masterpiece, essential to any heavy metal collection", while also displaying "a newfound sense of finesse and maturity". The album marked the band's fifth consecutive Platinum-selling album in the U.S., reaching number four on the UK Albums Chart and number 11 in the U.S.

The band began a world tour in January 1974, which culminated at the California Jam festival in Ontario, California, on April 6, 1974. Attracting over 200,000 fans, Black Sabbath appeared alongside popular 1970s rock and pop bands Deep Purple, Eagles, Emerson, Lake & Palmer, Rare Earth, Seals & Crofts, Black Oak Arkansas and Earth, Wind & Fire. Portions of the show were telecast on ABC Television in the U.S., exposing the band to a wider American audience. In the same year, the band shifted management, signing with notorious English manager Don Arden. The move caused a contractual dispute with Black Sabbath's former management, and while on stage in the U.S., Ozzy Osbourne was handed a subpoena that led to two years of litigation.

Black Sabbath began work on their sixth album in February 1975, again in England at Morgan Studios in Willesden, this time with a decisive vision to differ the sound from Sabbath, Bloody Sabbath. "We could've continued and gone on and on, getting more technical, using orchestras and everything else which we didn't particularly want to. We took a look at ourselves, and we wanted to do a rock album – Sabbath, Bloody Sabbath wasn't a rock album, really".

Produced by Black Sabbath and Mike Butcher,  Sabotage was released in July 1975. As with its precursor, the album initially saw favourable reviews, with Rolling Stone stating "Sabotage is not only Black Sabbath's best record since Paranoid, it might be their best ever", although later reviewers such as AllMusic noted that "the magical chemistry that made such albums as Paranoid and Vol. 4 so special was beginning to disintegrate".

Sabotage reached the top 20 in both the U.S. and the United Kingdom, but was the band's first release not to achieve Platinum status in the U.S., only achieving Gold certification. Although the album's only single "Am I Going Insane (Radio)" failed to chart, Sabotage features fan favourites such as "Hole in the Sky" and "Symptom of the Universe". Black Sabbath toured in support of Sabotage with openers Kiss, but were forced to cut the tour short in November 1975, following a motorcycle accident in which Ozzy Osbourne ruptured a muscle in his back. In December 1975, the band's record companies released a greatest hits album without input from the band, titled We Sold Our Soul for Rock 'n' Roll. The album charted throughout 1976, eventually selling two million copies in the U.S.

Black Sabbath began work for their next album at Criteria Studios in Miami, Florida, in June 1976. To expand their sound, the band added keyboard player Gerald Woodroffe, who also had appeared to a lesser extent on Sabotage. During the recording of Technical Ecstasy, Ozzy Osbourne admits that he began losing interest in Black Sabbath and began to consider the possibility of working with other musicians.

Recording of Technical Ecstasy was difficult; by the time the album was completed, Osbourne was admitted to Stafford County Asylum in Britain. It was released on September 25, 1976 to mixed reviews, and – for the first time – later music critics gave the album less favourable retrospective reviews; two decades after its release, AllMusic gave the album two stars, and noted that the band was "unravelling at an alarming rate".

The album featured less of the doomy, ominous sound of previous efforts, and incorporated more synthesisers and uptempo rock songs. Technical Ecstasy failed to reach the top 50 in the U.S. and was the band's second consecutive release not to achieve Platinum status, although it was later certified Gold in 1997.

The album included "Dirty Women", which remains a live staple, as well as Bill Ward's first lead vocal on the song "It's Alright". Touring in support of Technical Ecstasy began in November 1976, with openers Boston and Ted Nugent in the U.S., and completed in Europe with AC/DC in April 1977.

In late 1977, while in rehearsal for their next album and just days before the band was set to enter the studio, Ozzy Osbourne abruptly quit the band. Tony Iommi called vocalist Dave Walker, a longtime friend of the band who had previously been a member of Fleetwood Mac and Savoy Brown, and informed him that Osbourne had left the band. Walker, who was at that time fronting a band called Mistress, flew to Birmingham from California in late 1977 to write material and rehearse with Black Sabbath. On January 8, 1978, Dave Walker made his only live performance with Black Sabbath, on vocals, when they played an early version of the song "Junior's Eyes" on the BBC Television programme Look! Hear! Walker later recalled that, while in Birmingham, he had bumped into Osbourne in a pub and came to the conclusion that Osbourne was not fully committed to leaving Black Sabbath. "The last Sabbath albums were just very depressing for me", Osbourne said. "I was doing it for the sake of what we could get out of the record company, just to get fat on beer and put a record out." Walker has said that he wrote a lot of lyrics during his brief time in the band, but none of them were ever used. If any recordings of this version of the band other than the Look! Hear! footage still exist, Walker says that he is not aware of them.

Ozzy Osbourne initially set out to form a solo project featuring former Dirty Tricks members John Frazer-Binnie, Terry Horbury and Andy Bierne. As the new band were in rehearsals in January 1978, Osbourne had a change of heart and rejoined Black Sabbath. "Three days before we were due to go into the studio, Ozzy wanted to come back to the band", Tony Iommi explained. "He wouldn't sing any of the stuff we'd written with the other guy (Walker), so it made it very difficult. We went into the studio with basically no songs. We'd write in the morning so we could rehearse and record at night. It was so difficult, like a conveyor belt, because you couldn't get time to reflect on stuff. 'Is this right? Is this working properly?' It was very difficult for me to come up with the ideas and putting them together that quick".

The band spent five months at Sounds Interchange Studios in Toronto, Ontario, Canada, writing and recording what would become Never Say Die!. "It took quite a long time", Tony Iommi said. "We were getting really drugged out, doing a lot of dope. We'd go down to the sessions, and have to pack up because we were too stoned, we'd have to stop. Nobody could get anything right, we were all over the place, everybody's playing a different thing. We'd go back and sleep it off, and try again the next day".

The album was released in September 1978, reaching number 12 in the United Kingdom and number 69 in the U.S. Press response was unfavourable and did not improve over time, with Eduardo Rivadavia of AllMusic stating two decades after its release that the album's "unfocused songs perfectly reflected the band's tense personnel problems and drug abuse". The album featured the singles "Never Say Die" and "A Hard Road", both of which cracked the top 40 in the United Kingdom.

The band also made their second appearance on the BBC's Top of the Pops, performing "Never Say Die". It took nearly 20 years for the album to be certified Gold in the U.S.

Touring in support of Never Say Die! began in May 1978 with openers Van Halen. Reviewers called Black Sabbath's performance "tired and uninspired", a stark contrast to the "youthful" performance of Van Halen, who were touring the world for the first time. The band filmed a performance at the  Hammersmith Odeon in June 1978, which was later released on DVD as Never Say Die. The final show of the tour – and Ozzy Osbourne's last appearance with the band until later reunions – was in Albuquerque, New Mexico, on December 11.

Following the tour, Black Sabbath returned to Los Angeles and again rented a house in Bel Air, where they spent nearly a year working on new material for the next album. The entire band were abusing both alcohol and other drugs, but Tony Iommi says Ozzy Osbourne "was on a totally different level altogether". The band would come up with new song ideas, but Osbourne showed little interest and would refuse to sing them. Pressure from the record label and frustrations with Osbourne's lack of input coming to a head, Iommi made the decision to fire Osbourne in 1979. Tony Iommi believed the only options available were to fire Osbourne or break the band up completely. "At that time, Ozzy had come to an end", Tony said. "We were all doing a lot of drugs, a lot of coke, a lot of everything, and Ozzy was getting drunk so much at the time. We were supposed to be rehearsing and nothing was happening. It was like, 'Rehearse today? No, we'll do it tomorrow.' It really got so bad that we didn't do anything. It just fizzled out". Bill Ward, who was close with Ozzy, was chosen by Tony Iommi to break the news to the singer on April 27, 1979. "I hope I was professional, I might not have been, actually. When I'm drunk I am horrible, I am horrid", Bill Ward said. "Alcohol was definitely one of the most damaging things to Black Sabbath. We were destined to destroy each other. The band were toxic, very toxic".

While Don Arden was trying to convince Ozzy Osbourne to rejoin Black Sabbath, as he viewed the original line-up as the most profitable, the band hired former Rainbow frontman Ronnie James Dio as Osbourne's replacement, and they began writing their next album. With a notably different vocal style from Osbourne's, Dio's addition to the band marked a change in Black Sabbath's sound. "They were totally different altogether", Tony Iommi explains. "Not only voice-wise, but attitude-wise. Ozzy was a great showman, but when Dio came in, it was a different attitude, a different voice and a different musical approach, as far as vocals. Dio would sing across the riff, whereas Ozzy would follow the riff, like in "Iron Man". Ronnie came in and gave us another angle on writing."

Geezer Butler temporarily left the band in September 1979 to deal with the divorce from his first wife. According to Dio, the band initially hired Craig Gruber, with whom Dio had previously played while in Elf and Rainbow, on bass to assist with writing the new album. Craig Gruber was soon replaced by Geoff Nicholls of Quartz. The new line-up returned to Criteria Studios in November to begin recording work, with Geezer Butler returning to the band in January 1980 and Geoff Nicholls moving to keyboards.

Produced by Martin Birch, Heaven and Hell was released on April 25, 1980, to critical acclaim. Over a decade after its release, AllMusic said the album was "one of Sabbath's finest records, the band sounds reborn and re-energised throughout". Heaven and Hell peaked at number nine in the United Kingdom and number 28 in the U.S., the band's highest-charting album since Sabotage. The album eventually sold a million copies in the U.S., and the band embarked on an extensive world tour, making their first live appearance with Ronnie James Dio in Germany on April 17, 1980.

Black Sabbath toured the U.S. throughout 1980 with Blue Öyster Cult on the "Black and Blue" tour, with a show at Nassau Coliseum in Uniondale, New York, filmed for Don Kirshner's Rock Concert and later released theatrically in 1981 as Black and Blue. On July 26, 1980, the band played to 75,000 fans at a sold-out Los Angeles Memorial Coliseum with Journey, Cheap Trick and Molly Hatchet. The next day, the band appeared at the 1980 Day on the Green at Oakland Coliseum. While on tour, Black Sabbath's former label in England issued a live album culled from a seven-year-old performance, titled Live at Last without any input from the band. The album reached number five on the UK chart and saw the re-release of "Paranoid" as a single, which reached the top 20.

On August 18, 1980, after a show in Bloomington, Minnesota, Bill Ward quit the band. "It was intolerable for me to get on the stage without Ozzy. And I drank 24 hours a day, my alcoholism accelerated". Geezer Butler stated that after Bill Ward's final show, the drummer came in drunk, stating that "he might as well be a Martian". Ward then got angry, packed his things and got on a bus to leave. Following Ward's sudden departure, the group hired drummer Vinny Appice. Further trouble for the band came during their October 9, 1980 concert at the Milwaukee Arena, which degenerated into a riot that caused $10,000 in damages to the arena and resulted in 160 arrests.

According to the Associated Press: "The crowd of mostly adolescent males first became rowdy in a performance by the Blue Oyster Cult" and then grew restless while waiting an hour for Black Sabbath to begin playing. A member of the audience threw a beer bottle that struck Geezer Butler and effectively ended the show. "The band then abruptly halted its performance and began leaving" as the crowd rioted. The band completed the Heaven and Hell world tour in February 1981 and returned to the studio to begin work on their next album.

Black Sabbath's second studio album that was produced by Martin Birch and featured Ronnie James Dio as vocalist, Mob Rules, was released in October 1981 and was well received by fans, but less so by critics. Rolling Stone reviewer J. D. Considine gave the album one star, claiming "Mob Rules finds the band as dull-witted and flatulent as ever". Like most of the band's earlier work, time helped to improve the opinions of the music press. A decade after its release, AllMusic's Eduardo Rivadavia called Mob Rules "a magnificent record". The album was certified Gold and reached the top 20 on the UK chart. The album's title track, "The Mob Rules", which was recorded at John Lennon's old house in England, was also featured in the 1981 animated film Heavy Metal, although the film version is an alternate take and differs from the album version.

Unhappy with the quality of 1980's Live at Last, the band recorded another live album – titled Live Evil – during the Mob Rules world tour, across the United States in Dallas, San Antonio and Seattle, in 1982. During the mixing process for the album, Tony Iommi and Geezer Butler had a falling-out with Dio. Misinformed by their then-current mixing engineer, Tony Iommi and Geezer Butler accused Ronnie James Dio of sneaking into the studio at night to raise the volume of his vocals. In addition, Dio was not satisfied with the pictures of him in the artwork. Butler also accused Dio and Appice of working on a solo album during the album's mixing without telling the other members of Black Sabbath.

"Ronnie wanted more say in things", Iommi said. "And Geezer would get upset with him and that is where the rot set in. Live Evil is when it all fell apart. Ronnie wanted to do more of his own thing, and the engineer we were using at the time in the studio didn't know what to do, because Ronnie was telling him one thing and we were telling him another. At the end of the day, we just said, 'That's it, the band is over'". "When it comes time for the vocal, nobody tells me what to do. Nobody! Because they're not as good as me, so I do what I want to do", Dio later said. "I refuse to listen to Live Evil, because there are too many problems.

If you look at the credits, the vocals and drums are listed off to the side. Open up the album and see how many pictures there are of Tony, and how many there are of me and Vinny".

Ronnie James Dio left Black Sabbath in November 1982 to start his own band and took drummer Vinny Appice with him. Live Evil was released in January 1983, but was overshadowed by Ozzy Osbourne's Platinum-selling album Speak of the Devil.

The remaining original members, Tony Iommi and Geezer Butler, began auditioning singers for the band's next release. Deep Purple and Whitesnake's David Coverdale, Samson's Nicky Moore and Lone Star's John Sloman were all considered, and Iommi states in his autobiography that Michael Bolton  auditioned, though this claim has been disputed, with Butler suggesting that Iommi concocted the story as "a joke" and Bolton insisting it was "only a rumour".

The band settled on then-former Deep Purple vocalist Ian Gillan to replace Dio in December 1982. The project was initially not to be called Black Sabbath, but pressure from the record label forced the group to retain the name. The band entered The Manor Studios in Shipton-on-Cherwell, Oxfordshire, in June 1983 with a returned and newly sober Bill Ward on drums. "That was the very first album that I ever did clean and sober," Ward recalled.

"I only got drunk after I finished all my work on the album – which wasn't a very good idea... Sixty to seventy percent of my energy was taken up on learning how to get through the day without taking a drink and learning how to do things without drinking, and thirty percent of me was involved in the album."

Born Again (September 9, 1983) was panned on release by critics. Despite this negative reception, it reached number 4 in the UK, and number 39 in the U.S. Even three decades after its release, AllMusic's Eduardo Rivadavia called the album "dreadful", noting that "Gillan's bluesy style and humorous lyrics were completely incompatible with the lords of doom and gloom".

Unable to tour because of the pressures of the road, Bill Ward quit the band. "I fell apart with the idea of touring," he later explained. "I got so much fear behind touring, I didn't talk about the fear, I drank behind the fear instead and that was a big mistake." He was replaced by former The Move and Electric Light Orchestra drummer Bev Bevan for the Born Again '83–'84 World tour, (often unofficially referred to as the 'Feighn Death Sabbath '83–'84' World Tour) which began in Europe with Diamond Head, and later in the U.S. with Quiet Riot and Night Ranger.

The band headlined the 1983 Reading Festival in England, adding Deep Purple's "Smoke on the Water" to their encore. The Born Again Tour included a giant set of the Stonehenge monument. In a move later parodied in the mockumentary This Is Spinal Tap, the band made a mistake in ordering the set piece. Geezer Butler explained:

We had Sharon Osbourne's dad, Don Arden, managing us. He came up with the idea of having the stage set be Stonehenge. He wrote the dimensions down and gave it to our tour manager. He wrote it down in metres but he meant to write it down in feet. The people who made it saw fifteen metres instead of fifteen feet. It was 45 feet high and it wouldn't fit on any stage anywhere so we just had to leave it in the storage area. It cost a fortune to make but there was not a building on earth that you could fit it into.

Following the completion of the Born Again tour in March 1984, vocalist Ian Gillan left Black Sabbath to re-join Deep Purple, which was reforming after a long hiatus. Drummer Bev Bevan left at the same time, and Ian Gillan remarked that he and Bevan were made to feel like "hired help" by Tony Iommi. The band then recruited an unknown Los Angeles vocalist named David Donato and Bill Ward once again rejoined the band. The new line-up wrote and rehearsed throughout 1984, and eventually recorded a demo with producer Bob Ezrin (Alice Cooper among others) in October.

Unhappy with the results, the band parted ways with David Donato shortly after. Disillusioned with the band's revolving line-up, Bil Ward left shortly after stating "This isn't Black Sabbath". Geezer Butler would quit Sabbath next in November 1984 to form a solo band. "When Ian Gillan took over that was the end of it for me," he said. "I thought it was just a joke and I just totally left. When we got together with Gillan it was not supposed to be a Black Sabbath album.

After we had done the album we gave it to Warner Bros. and they said they were going to put it out as a Black Sabbath album and we didn't have a leg to stand on. I got really disillusioned with it and Gillan was really pissed off about it. That lasted one album and one tour and then that was it."

One vocalist whose status is disputed, both inside and outside Sabbath, is Christian evangelist and former Joshua frontman Jeff Fenholt. Fenholt insists he was a singer in Sabbath between January and May 1985. Iommi has never confirmed this. Fenholt gives a detailed account in Garry Sharpe-Young's book Sabbath Bloody Sabbath: The Battle for Black Sabbath.

Following both Bill Ward's and Geezer Butler's exits, sole remaining original member Tony Iommi put Sabbath on hiatus, and began work on a solo album with long-time Sabbath keyboardist Geoff Nicholls. While working on new material, the original Sabbath line-up agreed to a spot at Bob Geldof's Live Aid, performing at the Philadelphia show on July 13, 1985. This event – which also featured reunions of The Who and Led Zeppelin – marked the first time the original line-up had appeared on stage since 1978. "We were all drunk when we did Live Aid," recalled Geezer Butler, "but we'd all got drunk separately."

Returning to his solo work, Tony Iommi enlisted bassist Dave Spitz (ex-Great White), drummer Eric Singer (Kiss among others) and initially intended to use multiple singers, including Rob Halford of Judas Priest, former Deep Purple and Trapeze vocalist Glenn Hughes, and former Sabbath vocalist Ronnie James Dio. This plan did not work as he forecasted. "We were going to use different vocalists on the album, guest vocalists, but it was so difficult getting it together and getting releases from their record companies. Glenn Hughes came along to sing on one track and we decided to use him on the whole album."

The band spent the remainder of the year in the studio, recording what would become Seventh Star (1986). Warner Bros. refused to release the album as a Tony Iommi solo release, instead insisting on using the name Black Sabbath. Pressured by the band's manager, Don Arden, the two compromised and released the album as "Black Sabbath featuring Tony Iommi" in January 1986.

"It opened up a whole can of worms," Iommi explained. "If we could have done it as a solo album, it would have been accepted a lot more." Seventh Star sounded little like a Sabbath album, incorporating instead elements popularised by the 1980s Sunset Strip hard rock scene. It was panned by the critics of the era, although later reviewers such as AllMusic gave album verdicts, calling the album "often misunderstood and underrated". The new line-up rehearsed for six weeks preparing for a full world tour, although the band were eventually forced to use the Sabbath name.

"I was into the 'Tony Iommi project', but I wasn't into the Black Sabbath moniker," Glenn Hughes said. "The idea of being in Black Sabbath didn't appeal to me whatsoever. Glenn Hughes singing in Black Sabbath is like James Brown singing in Metallica. It wasn't gonna work." Just four days before the start of the tour, Hughes got into a bar fight with the band's production manager John Downing which splintered the singer's orbital bone. The injury interfered with Hughes' ability to sing, and the band brought in vocalist Ray Gillen to continue the tour with W.A.S.P. and Anthrax, although nearly half of the U.S. dates would be cancelled because of poor ticket sales.

Black Sabbath began work on new material in October 1986 at AIR Studios in Montserrat with producer Jeff Glixman. The recording was fraught with problems from the beginning, as Jeff Glixman left after the initial sessions to be replaced by producer Vic Coppersmith-Heaven. Bassist Dave Spitz quit over "personal issues", and former Rainbow and Ozzy Osbourne bassist Bob Daisley was brought in. Daisley re-recorded all of the bass tracks, and wrote the album's lyrics, but before the album was complete, he left to join Gary Moore's backing band, taking drummer Eric Singer with him.

After problems with second producer Vic Coppersmith-Heaven, the band returned to Morgan Studios in England in January 1987 to work with new producer Chris Tsangarides. While working in the United Kingdom, new vocalist Ray Gillen abruptly left Black Sabbath to form Blue Murder with guitarist John Sykes (Tygers of Pan Tang, Thin Lizzy, Whitesnake) and then Badlands with former Osbourne guitarist Jake E. Lee. The band auditioned a number of singers, including Jon Oliva of Savatage.
