Test Icicles were a short-lived rock band formed in the UK, primarily influenced by indie rock but containing musical elements from a variety of genres (notably hip-hop, crossover thrash and punk). The band was formed in 2004 by Rory Attwell and Sam Mehran. They were later joined by Devonte Hynes, who was originally invited to fill in at a performance in Brighton, England and afterward became a permanent member of the band. Devonte Hynes of the Test Icicles has since formed Lightspeed Champion.
