Sister is the fourth studio album by the American alternative rock band Sonic Youth, released on SST Records on June 1, 1987. The album represented a continuation of the band's evolution on their previous album EVOL, moving away from the no wave movement towards alternative rock song structures while maintaining an experimental approach. It was their first album with the lineup from the previous album intact, with Thurston Moore, Kim Gordon, Lee Ranaldo, and Steve Shelley all returning. The album, written while on tour and recorded in early 1987, is a loose concept album inspired by the life and works of writer Philip K. Dick. Like Sonic Youth's previous albums, Sister was not commercially successful at the time of its release, but received critical acclaim. Retrospectively, several publications have named it as one of the best albums of the 1980s.
