Madison, at 7:30 p.m. Saturday, March 12, on the tour supporting their fifth studio album, "The E.N.D.," which already has racked up sales of 3 million in the U.S. alone. Ludacris and LMFAO open, and tickets are $49.50 to $89.50 via www.ticketmaster.com, (312) 559-1212.

On a rare break between Wilco tours, that band's leader plays two shows this weekend at the Vic Theatre, 3145 N. Sheffield, starting at 8 p.m. Friday and Saturday, March 12-13. Jeff Tweedy's solo gigs always are a prime opportunity to hear him road-test new material and reinvent old favorites, and proceeds benefit a children's scholarship fun. Tickets still remain for $50 via www.ticketmaster.com or at the Vic box office, (773) 472-0449; other price points vary.
