Bloc Party are an English rock band. The band consists of Kele Okereke (vocals, guitar), Russell Lissack (guitar), Justin Harris (bass, vocals) and Louise Bartle (drums, vocals). In 2005, the band released their critically acclaimed debut album Silent Alarm and from there skyrocketed into success. Originally named Union in 2003 they changed their name to what we have always known them as Bloc Party. The name is a play on block party, a name for an informal neighbourhood festival, which might hire a local band as entertainment. The band have said that the name was not intended to be an allusion to the Soviet Bloc or the Canadian political party Bloc Québécois; the absence of a 'k' is purely for aesthetics.
