COMMON Let this soak in: Common's debut album "Can I Borrow A Dollar?" turned 20 this year. Twenty! While his filmography is quickly outpacing his discography, one thing Common hasn't let slip is his live show. The Chicago rapper isn't just an energetic performer; he's a student of the culture and channels the spirits of some of its greatest names. His sets quickly make you realize that the guy you're not quite buying as a second lead on the big screen has had top-flight bars for more than a decade. Recent appearances on G.O.O.D Music's Cruel Summer and as part of the Cocaine80s should erase any doubt that he lost his flow somewhere between his reading of scripts. Just imagine if he and Ice Cube, another public enemy-turned-media darling, decided to rekindle their beef for old time's sake. Though he's listed as a host of this holiday party, we're hoping (and betting) he'll take the stage for at least a handful of tunes. With DJ Dummy. $15. Dec. 22, 10 p.m. RE:Public, 314 N.
