I have yet to have the pleasure of seeing Wilco live (going to my first show next week in Brooklyn) but I did see Neil Young & Crazy Horse in the early 90s and it was a great show. He did simply filthy, disgusting, unspeakable things to his guitar. Rarely has a guitarist wrung so much from so little technical proficiency. Not sure if he's still a good live act but I would be really, really psyched for a joint Neil-Wilco show.
