Sister is an album by alternative rock band Sonic Youth, released in 1987 on SST Records. It was re-released in late 1994 on DGC. The album furthers the band's move away from noise rock towards more traditional pop structures, while maintaining an aggressively experimental approach. It received universally-positive reviews. A loose concept album (like its follow-up Daydream Nation), Sister was in part inspired by the life and works of science fiction writer Philip K. Dick. (The "sister" of the title was Dick's fraternal twin, who died shortly after her birth, and whose memory haunted Dick his entire life.) The album features aggressive noise songs such as "White Kross" and "Catholic Block," plus haunting noir ode "Pacific Coast Highway". The group has regularly played songs such as "Schizophrenia," "White Kross" and "Kotton Krown" long after the album's release. In 1989, Steve Albini's short-lived band Rapeman released a song called "Kim Gordon's Panties" in response to "Kotton Krown." CD bonus track "Master-Dik" is a strange rap song which mentions Ciccone Youth; its title is a reference to New York City mastering facility Masterdisk. As usual, Moore and Gordon handled most of the vocal duties on the album, but Ranaldo sang "Pipeline/Kill Time". The album was recorded entirely on analog tube equipment, giving it its characteristic "warm" vintage feel. Videos were shot for "Beauty Lies In The Eye" and "Stereo Sanctity."
