Wiki: Daydream Nation is the fifth studio album by American alternative rock band Sonic Youth, released on October 18, 1988. The band recorded the album between July and August 1988 at Greene St. Recording in New York City, and it was released by Enigma Records as a double album.

After Daydream Nation was released, it received widespread acclaim from critics and earned Sonic Youth a major label deal. The album was ranked high in critics' year-end lists of 1988's best records, being voted second in The Village Voice's annual Pazz & Jop poll. Daydream Nation has since been widely considered to be Sonic Youth's greatest work, as well as one of the greatest albums of all time, specifically having a profound influence on the alternative and indie rock genres. It was chosen by the Library of Congress to be preserved in the National Recording Registry in 2005.

Sonic Youth's standard songwriting method involved Thurston Moore bringing in melody ideas and chord changes that the band would spend several months fashioning into full-length songs. Instead of paring the songs down as the group did with previous records, the months-long writing process for Daydream Nation resulted in long jams, some lasting over half an hour. Several friends of the band, including Henry Rollins, had praised the band's long live improvisations and told the group that its records never captured them. With Moore on a writing spree, the album ultimately had to be expanded to a double album.

Sonic Youth recorded Daydream Nation at New York's Greene Street basement studio. The studio's engineer, Nick Sansano, was accustomed to working with hip hop artists. Sansano did not know much about Sonic Youth, but he was aware the band had an aggressive sound, so he showed the band members his work on Public Enemy's "Black Steel in the Hour of Chaos" and Rob Base and DJ E-Z Rock's "It Takes Two". The group embraced the sound of the records. Sonic Youth booked three weeks of recording time at Greene Street's Studio A, starting in mid-July 1988. The band paid $1,000 per day of studio time, which was the most the band had paid to record an album up to that point.

Due to the amount of preparation the band put into composing its music, the recording process was efficient.The session became rushed near the end, when Paul Smith, the head of the band's British label Blast First, had set a mastering date of August 18. As a result of the time pressure, Gordon was not happy with some of her resulting vocal takes. The band spent a whole night creating a final mix for the three-song "Trilogy" so it could be mastered the following morning. The record ultimately cost $30,000, which led Moore to refer to the album as "our first non-econo record".
