Psycroptic is a metal band from Hobart, Australia. The band is currently signed to Prosthetic Records and have released eight full-length albums. They formed in 1999 by brothers Dave (drums) and Joe (guitar) Haley who had previously been involved in a band called Disseminate. That group had recorded a demo in 1998 before disbanding. Shortly afterward, the Haleys created Psycroptic with Cameron Grant on bass and vocalist Matthew Chalk, who soon after became a drummer with established local death metal act M.S.I.
