Red Square is an English free improvising, experimental rock band originally from Southend-on-Sea, Essex, England, that formed in 1974 and broke up in 1978, before reforming again in 2008 as a result of renewed interest in their music. The line up has remained unchanged, consisting of Ian Staples (electric guitar), Jon Seagroatt (soprano saxophone, bass clarinet, flute and electronics) and Roger Telford (drums and percussion).
