3. 'Heart-Shaped Box'
In a 1994 interview with Rolling Stone, Courtney Love recalled hearing Kurt work on "Heart-Shaped Box." "We had this huge closet," she said. "And I heard him in there working on 'Heart-Shaped Box.' He did that in five minutes. Knock, knock, knock. 'What?' 'Do you need that riff?' 'Fuck you!' Slam. [Laughs] He was trying to be so sneaky. I could hear that one from downstairs." He'd been picking away at the track since early 1992, and it ultimately wound up as the first single from In Utero. The album was produced by Steve Albini, but the label worried it wasn't commercial enough, and Scott Litt was brought in to remix "Heart-Shaped Box." Last year, Love claimed the song was written about her vagina.
