Who opened for the avett brothers New Year's Eve in 2006?

That's a tough one. Here's a hint. One of the bands was based out of Wilmington, NC while the other was from Johnson City TN. I checked back and the opening acts names are printed on the bottom of the limited art print Acott did for that show. You can find it @ http://entertainment.webshots.com/album/556417366DLUJHU
