If you're a casual fan or higher, please take my word for this and head over to Wilcoworld.net. Click on the "roadcase" tab and listen to one of the most inspired shows of Wilco's career. It is a full show from the Civic Opera House in Chicago, recorded on 12/12/11, and it is streaming for free.
A killer set list with amazing sound and just a band on fire.
