How funny - I just saw a similar post on Katie Phelan's blog. Did you see them there by chance? I had to google the group as I'm so "unhip" I'd never heard of them!
Sarah, we were at this show too...I LOVE them and can't quite get enough of their music. It was such a perfect way to spend an evening - fabulous music, good beer and time with my sweetie. Glad to hear that you enjoyed it too (and are familar with the Avett Brothers - everyone I tell about the concert has never heard of them).
