In utero

Though Nevermind was Nirvana's most commercially successful album, and the record that broke them - and the grunge phenomenon - internationally, In Utero has increasingly become regarded as the band's best album, both by the critics and the band members themselves.

Here, the full story behind the creation of In Utero is told for the first time.
