Bitches Sin were a legendary heavy metal band, based in the north of England, and formed around 1980. After several changes, the definitive line-up of Ian Toomey, Pete Toomey, Frank Quegan, Billy Knowles and Mike Frazer, came together and produced some of the most influential heavy metal music of the 80's. This culminated in the cult classic, 'Invaders' album, released in 1986, which received rave reviews from Aardshock's Readers Poll, amongst many others. Invaders was essential listening for skate boarders across the USA. Often quoted 'skate or die'.
