Ah, Wilco.
As far as I'm concerned, Yankee Hotel Foxtrot is the best album Wilco has and will ever release, with Summerteeth taking close 2nd. I like A Ghost Is Born, but it can't touch either YHF or Summerteeth.
I saw them live this past summer, and while they played a great show and it was a lot of fun, I would have rather seen them before Ghost came out, or even before YHF. They only played two tracks from Summerteeth, which was dissapointing.
They cancelled the live DVD and are working on their next album. My guess is they'll go more and more "experimental" like they did with Ghost. Ah, well.
