It’s the 20th anniversary of Nirvana’s final record, "In Utero," released in September 1993. Kurt Cobain wanted the album to sound less like a pop record so the band brought in producer Steve Albini.
But the record company thought the results were too harsh. Another producer did the final mix. To mark the anniversary, there’s new deluxe edition of the album out that includes the rougher original mixes. Ross Reynolds and music writer Charles Cross discuss the impact and influence of "In Untero."
