Nevermind is the second studio album by the American rock band Nirvana, released on September 24, 1991. Produced by Butch Vig, Nevermind was the group's first release on Geffen Records, which signaled its move away from Seattle-based independent record label Sub Pop. Front man Kurt Cobain sought to make music outside of the restrictive confines of the Seattle grunge scene, drawing influence from groups such as the Pixies and its use of loud/quiet song dynamics.

Nevermind was a surprise success by late 1991, largely due to the success of its lead single "Smells Like Teen Spirit". By January 1992 it had replaced Michael Jackson's album Dangerous at number one on the Billboard charts. Nevermind was responsible for bringing alternative rock to a large mainstream audience, and would subsequently be regarded as one of the best rock albums of all time.
