Here is a cut from the new M. Ward album, a cover of Daniel Johnston's "To Go Home," a rollicking, thrusting (uh huh huh huh) rocker just full of energy. Download it here. You can download the full album on the excellent music site emusic.com.
Muzzle of Bees, one of my favorite MP3 blogs is hosting a new Wilco tune, "There's a Light". Download it here. It's a live cut, but the sound is pretty good.
Also, rbally is an excellent mp3 blog which is heavy on the Wilco.
