So, I have been obsessed with Josh Ritter for the last few years, ever since I saw him open for Keane in Boston. He's a singer-songwriter whose songs are incredible and whose performances are a joy to witness. He's got huge rabid fans, but hasn't really hit it big in mainstream music (which is both good and bad). Well, NPR discovered him about a year ago and just yesterday, they did a piece on him and Hilary Hahn, a classical violinist, performing at the Metropolitan Museum of Art in New York City. It's really amazing. You have to check it out.
