Hellrazer was formed in mid 2004 by guitarists DrZ and Hoss. After recruiting a bassist and current drummer Kegger, the band began to focus on writing original material rather than being a cover band. In 2007, Hellrazer completed their first self-produced full length album entitled "Hellrazer". In late 2008, two original founding members left the band, and were replaced by lead guitarist Stan Nakanishi and bassist Dan Houser who are featured on Hellrazer's second self-produced CD entitled "Prisoner of the Mind". The album received overwhelmingly positive reviews around the globe, and charted well on a number of Canadian university and college radio stations. Hellrazer played numerous shows in Alberta to promote the CD, but in 2010 Dan moved to Toronto, leaving the remaining band members to focus on writing new material. Hellrazer auditioned a number of bass players before selecting Simon Hirota. During this period, the band was noticed by Dust on the Tracks Records who signed Hellrazer for the release of their third album entitled "Operation Overlord". The album was recorded at Alchemy studios and features 10 new metal anthems plus two re-recorded songs from their debut CD as bonus tracks. For mastering, Hellrazer recruited legendary produced Michael Wagener, and the album was released in February and distributed by Universal and Sony music, respectively in North America and Europe. "Operation Overlord" was nominated for a Western Canadian Music Award for best metal recording.
