Gang of Four are an English post-punk group from Leeds. Original personnel were singer Jon King, guitarist Andy Gill, bass guitarist Dave Allen and drummer Hugo Burnham. They were fully active from 1977 to 1984, and then re-emerged twice in the 1990s with King and Gill. In 2004, the original line-up reunited but in 2006 Allen was replaced on bass by Thomas Mcneice and later Burnham on drums by Mark Heaney.
