Diablo Swing Orchestra
On March 29, 2012, he left the band Diablo Swing Orchestra feeling he couldn't "mobilize that amount of greatness and enthusiasm, without having a bigger share of the artistic creation and in addition to limited financial gain. I just have too much other things going in my life right now. And I really want to continue working on my own projects." Petter's statement was published on Diablo Swing Orchestra's Facebook page
In 2008, Petter Karlsson launched his own project called Holocoaster. Self-styled as Murder rock/Killer metal, launched a video clip for the song "Another day - Another victim". "The last year I've received hundreds of mails from fans begging me to come up with something new .This is the first time I've ever been able to put 110% effort, commitment, blood and tears into my music without any compromises." Later in 2014 the song Mani-Jack was featured on the Swedish Encyclopedia "The Heaviest Encyclopedia of Swedish Hard Rock & Heavy Metal Ever!" where the book author misspelled the band's name. A final statement was posted via Revernation were Petter Karlsson explains the reason why the band didn't make further and released 5 songs from the unfinished debut album to listen and download for free
