Muzzle of Bees has two new Wilco songs recorded at a benefit concert; FYI, they'll also be playing Madison on Saturday. I haven't seen them since YHF but it was a fine show.
Speaking of bootleg Wilco and YHF, the demo/alternate version is worth tracking down. The version of "Poor Places" off those cuts might be my favorite Wilco song.
