The venerable alt-country label (it invented the genre, don'tcha know) throws its hometown a 20th birthday bash. One more year, and it can finally drink whiskey! There's a killer lineup assembled. Current starlet Lydia Loveless brings her tough and tender tunes. Ben Kweller does his lovelorn power-pop. Original queen Kelly Hogan sings. As do Sally Timms, Rhett Miller, Bobby Bare Jr. and new signee Banditos. Plus: a magician! One of the must-see shows of January.
