on Dirty. The latter tour was chronicled on the documentary 1991: The Year Punk Broke, directed by Dave Markey. In November, they began demoing songs on 8-track at their rehearsal space in Hoboken. Recording For Dirty, Sonic Youth worked with producer Butch Vig and mixer Andy Wallace, who both had worked in the same roles on Nirvana's Nevermind, although this was not why the band chose them. On the album's sound, Pitchfork would later opine that "they weren't entirely catering to the new ears Nirvana's success was sending their way", but "were at least taking it into consideration on a semi-conscious level". During his first meeting with the group, Vig told the band that he wanted to tighten the song arrangements and focus on crafting the guitar sounds. Vig quickly landed the producer job for the record. During a visit to the apartment of Sonic Youth members Thurston Moore and Kim Gordon, Moore told Vig he wanted the album to sound like an obscure Mecht Mensch single that Vig had produced. The band sent a series of cassette tapes to Vig in late 1991, featuring their new compositions. Vig was pleased but also uncertain, as the tapes consisted of long instrumentals, and the producer was unable to discern the song structures. The second batch of cassettes that Vig received demonstrated that the band had performed some self-editing with its compositions. Vig moved to New York City for three months in early 1992 and the band began recording the album at the Magic Shop in March. Ian MacKaye of Fugazi contributed guest guitar on "Youth Against Fascism". The last song on the album, "Crème Brûlée", was recorded when Gordon was randomly playing guitar and singing with Shelley playing the drums, while Moore was trying to turn on his amplifier and guitarist Lee Ranaldo was recording the whole thing. After recording was completed, the album needed to be trimmed down from 18 tracks. Moore, Gordon and the band's A&R person, Gary Gersh, agreed that Ranaldo's song "Genetic" would be removed. Ranaldo did not react well to the decision; coupled with personal issues he was facing at the time, it led him to consider leaving the group. After a few weeks, the matter settled and Ranaldo stayed with the band. "Genetic" and another omitted track, Gordon's "Hendrix Necro", were instead featured on the "100%" single. Another track recorded in the sessions, "Stalker", was
