The Avett Brothers: Tiny Desk Concert : NPR - This is an older concert (from 1999 I think) that is really good. Gives a good idea of how a concert would be. The middle song - Down with the Shine - is one I've never heard and apparently isn't on any album yet. Again, this whets my appetite for going to a show. This music always makes me want to pick up my guitar and play along.
