For some odd reason, even the threat of imprisonment won't keep R. Kelly from sharing his music with the world. Lucky us. That and the fact he constantly sells millions of albums is probably what prompted Rowe Entertainment Inc. to sponsor this year's Double Up Tour. "Mr. Show Piss (oops, meant Biz)" will be joined by up-and-comers Keyshia Cole and J. Holiday, hot off the success of their latest, Just Like You and Back Of My Lac, respectively. Wonder how many chapters of Trapped in the Closet the audience will be forced to stomach? Probably not many, as Mr. Kelly will be much too busy checking for his next conquest. Parents of girls ages 12-16, be warned. 7:30 p.m. $45-$100. Charlotte Bobcats Arena, 333 E. Trade St. 704-522-6500. www.charlottebobcatsarena.com.
