The former Hüsker Dü/Sugar frontman Bob Mould is a punk rock legend, and it turns out that he’s also really, really great at performing on late-night TV talk shows. Remember when he ripped through “I Don’t Know You Anymore” on Conan? Jesus. Ridiculous. Last night, Mould was on Jimmy Kimmel Live, and he once again rocked hard enough that I’m worried he’s going to break something one of these days. Mould usually plays with Superchunk drummer Jon Wurster, but last night, he had a ringer behind him, as Foo Fighters drummer Taylor Hawkins filled in.
