My roommate is a huge Conor/Bright Eyes fan, so I've heard just about everything the man has released. I was never big on Bright Eyes, but Conor's two solo albums with the Mystic Valley Band are very good. It's a different vocal style (less yelpy), and the music seems like it would appeal to a Wilco crowd.
But I could be wrong. Either way, I'm pretty excited for this show.
