Osyron is a Canadian metal band based in Calgary/Edmonton, Alberta. The band was founded under the name Morbid Theory, and now consists of Bobby Harley (vocals, guitar), Krzysztof Stalmach (guitar), and Curtis Manzys (drums).

They wrote their first demo, Chaos Breed, and released it in December 2006. Since that release, Osyron, performing under the name Morbid Theory, have dedicated themselves to enhancing their quality and sound by performing multiple shows and small tours alongside successful bands like Norther, Protest the Hero, Threat Signal, Quo Vadis, and The Agonist.

Beginning summer 2009, the band began writing material for their first full-length album, Harbinger. They recorded a demo of it at Ice House Studios (Goderich, Ontario) and released it digitally in August 2010.

Following a line-up change in 2012, the band felt they needed a fresh start with their new ideas. Their title was changed to Osyron, and the band moved from Ontario to Alberta.

Harbinger was re-recorded under the new name in February-March of 2013 at Perfect Fifth Studios in Calgary, Alberta and was released on June 4, 2013.
