Morbid Theory (2004-2012): a Death Metal band from Sarnia, Ontario, Canada.
Sarnia, Ontario act Morbid Theory started out in 2006 playing melodic death metal. They had planned to start life by releasing a demo called Seven Sins, but it was later scrapped and the band started anew, writing material for their debut full-length, Harbinger (2010) featuring the membership of Bobby Harley (guitars), Kris Stalmach (guitars), Dave Bauman (keyboards), Bobby Redman (vocals) and Curtis Manzys (drums; joining in 2011 after the release) but not before the release of Chaos Breed EP (2006). Previously the membership had featured Mike Bauman, Nick Lewis and Jake Burton on drums, and Adam Stalmach (guitars/vocals) and Korie Sheffer (vocals).
In 2012 the act folded with Manzys, Stalmach and Harley moving to Calgary, Alberta and re-open as Osyron.
