A DIFFERENT BREED OF KILLER, named after description given to Jack the Ripper by the inspector Frederick Abberline character portrayed by Johnny Depp in the movie 'From Hell', is a Knoxville, Tennessee based Deathcore band forged during October 2006. The group's first foray into the recording studio resulted in the 2007 two track 'Soundlair' demos.At this juncture A DIFFERENT BREED OF KILLER sported two lead vocalists. However, in late 2007 band members bassist Kyle McNulty and singer Patrick Hamilton exited. Louie Thal was newly inducted on bass and the band decided on persevering with one singer, Jesse Mainor.

Signing to Rise Records, the band recorded the April 2008 conceptual album 'I, Colossus' with producer Jamie King at Basement Studios in Winston-Salem, North Carolina. Phil Bozeman, from WHITECHAPEL, acted as guest vocalist on the song 'The Cleansing Apparatus'. The album artwork was executed by Chris Rubey from THE DEVIL WEARS PRADA.

National touring across the USA saw A DIFFERENT BREED OF KILLER sharing stages with IMPENDING DOOM, WHITECHAPEL and THROUGH THE EYES OF THE DEAD prior to commence fresh recording sessions for an EP utilising Soundlair Studios in March 2009.
