Wilco definitely kicks ass. They are, as already said, an alt-country band that sort of leans more to either side depending on the album. Fabulous fabulous music, and for it Jeff Tweedy and the boys are fairly well known among people who bother to find music that's not overplayed on MTV. I rather do prefer Summerteeth meself.
Wilco kicks huge ass. This 'Ben' fellow rules.
