I'm writing this as someone that is not a particularly huge Wilco fan. For me they have always been one of those groups that I could listen to, but never preferred. If they are playing in the background, I'm not going to get annoyed by it... you get the point.
I was there to see Blitzen Trapper mostly, and they put on a great set, it seemed short but Wilco was definitely the main act. They played a long set and even had two encores. The vocals were spot on, and they had some great guitar work. The entire group was grooving, and the audience was entirely positive and there was a great vibe all around. Overall a fantastic evening of entertainment and I will be looking to go again (hopefully for the whole weekend) next year.
