FAVORITE SON: Straight outta Oak Park, it's John Mahoney (yup, Frazier's grumpy pop) starring in "The Seafarer," a new Steppenwolf production. Catch tonight's preview of this dark comedy by Irish playwright Conor McPherson. 7:30PM, $40.
VOICE OF PLEASIN': Are you in dire need of some soul-stirring, hit-you-like-a-ton-of-bricks live music? Who isn't? Head to the Vic Theatre tonight to hear Sharon Jones and The Dap Kings, a real-deal, nine-piece R&B and soul band from Brooklyn that will blow your mind and move your behind simultaneously. 8PM, $22.
GETTIN' JAZZY WIT IT: See DJ Jazzy Jeff live and in person spinning '80s and '90s dance music tonight at the weekly "Old School Rewind" party at the Underground. Other flashbacks include grilled cheese and PB&J sandwiches and Kool-Aid cosmopolitans. It's like a high school house party all over again. 9PM-4AM; $20, email VIP@rockitranch.com for reduced cover.
