Released as part of a Back To Black reissue series for Sonic Youth's back catalogue, Goo is the sixth studio album by American alternative rock band Sonic Youth. It was originally released on June 26, 1990 and was Sonic Youth's debut release on a major record label, after the band signed to Geffen Records following the release of Daydream Nation (1988). It was recorded over a short period in early 1990 at Sorcerer Sound Recording Studios and Greene St. Recording with Daydream Nation producer Nick Sansano and additional producer Ron Saint Germain. The album's sound diverged considerably from their earlier material and is often considered "their most accessible album", with elements of experimental rock, garage punk, alternative rock and hard rock. Lead single "Kool Thing" charted in the United States, United Kingdom and Ireland.
