In 2007, the band was joined by the vocalist Charlie Holmes, bassist Jamie O'Rourke and drummer Max Blunos; and signed to Rising Records after paying the label a large fee.

The debut album, Purgation, was released in early 2008[1][2] and the band gained praise from the English press, in particular Kerrang!, Terrorizer and Metal Hammer magazines.

[3] The band supported Suffocation, Meshuggah and Cryptopsy on tour from mid- to late 2008,[5] performed at the Download Festival[6] and began work on their second album, The Great Depression.

Following the May 2010 release, the band embarked on a headlining European Degenerate tour[8][9] and appeared at the 2010 Download Festival, alongside A Day to Remember and Bullet for my Valentine.
