Steve said Sonic Youth was one of his favorite bands on some Big Black tour diary. Thurston, at the beginning of White Cross from "Hold that Tiger": "This is the Big Black reunion song." Kim Gordon's Panties is from when Kim threw her leopard print panties to Steve Albini. In retaliation, Sonic Youth tied up Steve at a Rapeman show with electric chords. As a joke. They have a very joking rivalry. Steve said in an interview that he hated Sonic Youth "selling out" and making lesser music when they signed to a major. But I don't think he holds it against them. I think they have a friendly rivalry, and Steve has just noted that SY doesn't make the kind of music they used to make.
