If elected, Tim Kaine will be the most music-savvy VP in American history. He plays blues harmonica, and he's an obsessive listener who keeps up with new artists (current indie fave: Lucy Dacus). "When I first ran for governor of Virginia I started playing with bluegrass bands all over the state because we have so many festivals," he says on the phone from the campaign trail. "I have six in my briefcase at all times. Even though I'm not very good, bands just kept saying, 'Come on up.'" We asked him to list his five favorite artists, in no particular order. "Twenty would have been easier," he says. "But this is more fun than lots of other stuff I have to talk about."
