Stereolab are an Anglo-French avant-pop band formed in London in 1990. Led by the songwriting team of Tim Gane and Lætitia Sadier, the group's sound features influences from krautrock and 1960s French pop music, often incorporating a repetitive motorik beat with the use of vintage electronic keyboards and female vocals sung in English and French. Their lyrics have political and philosophical themes influenced by the Surrealist and Situationist art movements. While performing, they play in a more feedback-driven and guitar-oriented style. From the mid-1990s, the band began to draw from funk, jazz and Brazilian music.
