I caught a short documentary called Big Easy Express over the weekend. The film covers a cross country music tour (via a train) starting in Oakland CA and ending in New Orleans. The tour had three acts, Mumford & Sons, Edward Sharpe and the Magnetic Zeros, and Old Crow Medicine Show. Here's the trailer.
I'm not sure how I missed them, but this is the first time I had heard of Old Crow Medicine Show. They have a fun folks sound and I wanted to share. Enjoy!
