Chaos UK are an English hardcore punk band formed in 1979 in Portishead, near Bristol. They played fast aggressive hardcore punk rock initially. The original line up of Simon Greenham on vocals, Andy on guitar, Chaos (aka "Lice") on bass and Potts on drums recorded two EP's and a full LP for Riot City Record. In the process they along with fellow Bristolians Disorder and Stoke's Discharge revolutionised the hardcore punk scene. In particular the Japanese 80's hardcore punk bands were heavily influenced by Chaos UK and Disorder's brutal take on punk. Chaos UK's debut LP was notable in the fact that the band's label claimed it was the "fastest, noisiest LP in the cosmos" in the short lived "Punk Lives" magazine; vocal duties on this recording were also handled by bassist Chaos.
