In the newest issue of Spin, Steve Earle and Will Sheff of Okkervil River have an epic discussion on the nature of "folk" music, and "Americana." It's worth a read, and you should support print journalism, or whatever. But here's a video version of that discussion, where Sheff and Steve Earle perform songs from their recent albums (I Am Very Far and I'll Never Get Out of This World Alive, respectfully) in NYC. The performances are earnest, beautiful and awesome. Watch them here.
