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 November 2006 Allen was replaced on bass by Thomas McNeice and Burnham on drums by Mark Heaney. They play a stripped-down mix of punk rock, funk music and dub reggae, with an emphasis on the social and political ills of society. Gang of Four are widely considered one of the leading bands of the late 1970s/early 1980s post-punk movement. Their later albums (Songs of the Free and Hard) found them softening some of their more jarring qualities, and drifting towards dance-punk and disco. Their debut album, Entertainment!, ranked at Number 490 in Rolling Stone''s The 500 Greatest Albums of All Time, and is listed by Pitchfork Media as the 8th best album of the 1970s. David Fricke in Rolling Stone said "Gang of Four are probably the best politically motivated band in rock & roll."
