Twenty years ago, Nirvana's third and final studio album, In Utero
, was released. When it came out, it represented both progress, in terms of songwriting (a huge leap in lyrical quality as compared to 1991's Nevermind
), and a simultaneous step back into the band's gritty, punk-rock roots. Legendary indie producer Steve Albini's productions were fantastically raw, but contentious. After higher-ups at the record company complained, Nirvana remixed several of the songs to make them more radio friendly ("[We had] obligations as a 'professional rock band' and as 'unit shifters'," said bassist Krist Novoselic in a recent NPR interview).
