Bloc Party are an English rock band that was formed in London in 1999 by co-founders Kele Okereke and Russell Lissack. Their first four albums all featured Gordon Moakes and Matt Tong (drums), who have since left the band. Their current lineup also contains Louise Bartle and Harry Deacon. Their brand of music, whilst rooted in rock, retains elements of other genres such as electronica and house music.
