He likes a day in the studio to end, he says, "when my knees are all skinned up and my pants are wet and my hair's off to one side and I feel like I've been in the foxhole all day. I don't think comfort is good for music. It's good to come out with skinned knuckles after wrestling with something you can't see. I like it when you come home at the end of the day from recording and someone says, "What happened to your hand?" And you don't even know. When you're in that place, you can dance on a broken ankle.
