" 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.
