In September 1991 Nirvana released Nevermind, an album which changed music for a generation. It swept away the last shreds of hair metal and opened hearts and minds to alternative rock.

At that time Nirvana was a relatively unknown alternative rock three-piece from the state of Washington, in North West USA. Their debut album on Sub-Pop, Bleach, had sold modestly and when single Smells Like Teen Spirit was released, nobody was prepared for the frenzy that followed.

Nevermind initially failed to trouble the charts on its release on 24 September 1991 but began to pick up sales on the back of the relentless and growing popularity of Teen Spirit. By January 1992 the album had knocked Michael Jackson off the number 1 slot. It went on to shift more than 30 million copies worldwide and defined how rock music sounded during the 90s.

In this programme, Dave Grohl, Krist Novoselic and Butch Vig talk to Steve Lamacq about the heady days of Nevermind's gestation and the explosive times following its release.

This documentary first broadcast on 6 Music in September 2011, 20 years after Nevermind was released.
