Hole continued to write material throughout the recording sessions over the ensuing weeks: "We never finished writing; we were writing the whole time, trying to come up with more and more songs because even though it looked like we had a good, solid album, we knew we were missing some pieces. We were still writing intensely and frantically putting songs together. It wasn't like, "Oh we have these 12 songs, they're done, and we're going to go in and record now."" The first week of recording was spent recording basic tracks, including drums, bass, scratch guitars, and scratch vocals. After basic tracks were completed, Love's husband, Cobain, visited the band in-studio before Nirvana were set to tour to promote In Utero. While there, the band invited Cobain to sing backing vocals on several tracks, which he initially refused, due to being unfamiliar with the material. When Cobain asked, "how can I sing on it if I haven't heard it?", Love answered by encouraging him to "just sing off the top of [his] head". Cobain is known to have provided backing vocals to "Asking for It" and "Softer, Softest", however Kolderie has said Cobain "sang on about five or so [tracks in total], probably "Violet", "Miss World" and "Doll Parts", I can't remember any of the others." After taking a break for dinner, the session devolved into a "formless jam" with Cobain on drums, Love and Erlandson on guitars and producer Sean Slade on bass. Musician Dana Kletter was asked to sing backing vocals on the record, and appears on seven songs, including "Violet", "Miss World", "Asking for It", "Doll Parts", "Softer, Softest", and "She Walks on Me". Producer Slade said, "I think one of the reasons that "Doll Parts" might have been a hit is that harmony Dana does on the "You will ache like I ache" part, it's almost like an Appalachian close harmony against what Courtney is doing. It's very melancholic." Slade and Paul Koderie avoided doubling Love's vocals, as they felt it "took the fierceness away". Certain imperfections were also left in the final mixes, including Love's voice cracking in "Doll Parts", which Geffen executives had originally requested be removed. According to Schemel, during the sessions an employee at Triclops Sound Studios offered them "an abundance of crystal meth". Schemel, her brother Larry Schemel and bassist Pfaff would get high during the recording. "Miss World" was one
