Surfer Rosa is the first full-length album by the American alternative rock band Pixies, released in March 1988 on the British independent record label 4AD. The album's unusual and offbeat subject matter includes references to mutilation and voyeurism; this is augmented by experimental recording, low-fidelity production and a distinctive drum sound. Surfer Rosa contains many of the themes present in the Pixies' earlier output, including Spanish lyrics and references to Puerto Rico. Surfer Rosa is often cited as a favorite of music critics, and is frequently included on professional lists of the all-time best rock albums. Many alternative rock artists, including PJ Harvey and Billy Corgan, have cited the album as inspirational; Nirvana's Kurt Cobain frequently acknowledged that Surfer Rosa was a strong influence on Nevermind, and in 1993 hired the album's producer Steve Albini to produce his band's album In Utero.
