After Forever member Sander Gommans suffered a burnout in the beginning of 2008. Floor Jansen posted on her website that while the band was put on hold, she was going to use the opportunity to start writing music with, Jørn Viggo Lofstad for a new musical project. On February 2009, After Forever ultimately decided to call it quits, and on June 16, 2009, Floor announced through her MySpace site that she had started a new metal band, which put her musical project with Jørn Viggo on hold.
On October 17, of 2009, Floor announced that the name of the band was going to be ReVamp.
Floor Jansen wrote all the music for their self-titled album in 2009. She collaborated with her old After Forever bandmate, Joost van den Broek and Grip Inc guitarist Waldemar Sorychta. The trio wrote and recorded everything, while Koen Herfst (I Chaos, Bagga Bownz, Armin van Buuren) recorded the drum tracks.
Afterwards, Floor Jansen recruited new band members for a live band. In 2010, their first album got released under Nuclear Blast. The band began to tour around The Netherlands and had many successful club shows and festivals. ReVamp joined Epica on their European tour.
Floor Jansen's health began to decline, thus she had to stop working and teaching. Since her health issues turned for the worse, all concerts were cancelled. Floor was diagnosed with a burnout herself just like her former bandmate. The band was inactive for quite sometime. By the end of 2011, Floor Jansen finally joined Mayan for one Brazilian show. She had not recuperated, but she was close to a full recovery.
ReVamp began writing new songs for their second album which was scheduled to be released in the spring of 2013. On October 2012, Finnish symphonic metal band Nightwish contacted Floor Jansen to join them for their remainder Imaginaerum World Tour since they had parted ways with former vocalist Anette Olzon. Because of her commitment to Nightwish, the band postponed the release of their upcoming installment to the fall of 2013.
ReVamp entered the studio in the beginning of the year. The album was announced to be scheduled for release in August 2013, again through Nuclear Blast. Jaap Melman decided to quit the band and the decision had a mutual understanding for both parties involved.
Since Jaap Melman left before any recordings were done for their next album, Stream of Passion bassist, Johan van Stratum filled in on short notice. Soon after, Henk Vonk was announced as ReVamp's newest bassist. On June 7, the band announced via Facebook that their new album would be called Wild Card.
The album features several guest musicians. This includes Johan van Stratum, Mark Jansen of Epica, Marcela Bovio of Stream of Passion, Daniël de Jongh of Textures, and finally Devin Townsend of Strapping Young Lad and The Devin Townsend Project.
On October 2013, Floor was hired as an official member of Nightwish (along with instrumentalist Troy Donockley) and spent half of 2014 and 2015 recording and preparing the release of their album, Endless Forms Most Beautiful.
When asked if ReVamp was on hiatus, she answered "It is, it has to be", because she doesn't wish to perform in both bands at the same time if she's unable to give 100% of her devotion and time.
Once we're done with this Nightwish tour we'll have to sit together and see where everybody is in their lives, and see if there's a chance to continue. It would be great, but I can't tell the future.
On September 29, 2016, a post was made to the group's official Facebook page informing fans that they had disbanded. The post read "We are sad to inform you that ReVamp has officially stopped.
After two great albums it is unfortunately not possible for the founding front lady, Floor Jansen to have a band next to Nightwish. Projects perhaps, but a band deserves a 100% devotion which is impossible to deliver to two bands at the same time."
Floor added: "I am proud of the 2 albums we made together! ReVamp has such talented and great musicians that I wouldn’t want them to wait any longer for me to find the time and the passion it needs to make another album.
I also don’t want to give fans false hope. ReVamp lived a short and bumpy but exciting life but now it’s time for new bands and projects to start. I thank everyone involved for the love and dedication!"
