Tuesday, August 2 MC Chris, he of the nasally voice and frequent guest-starring roles on Cartoon Network's Adult Swim block of programming, is often pigeonholed as "that nasally rapper from the Cartoon Network show." An easy mistake, and one that doesn't take into account his remarkable ability to rhyme (or, as the kids say, "flow"). MC Chris' best line just may be "My backpack's got jets/I'm Boba the Fett/I bounty hunt for Jabba the Hutt/to finance my 'Vette," or it may be contained in a rhyme yet to busted. The point is, MC Chris' fixation on rapping about the Star Wars trilogy, role-playing games and other nerdly pursuits is no less ridiculous than all this posturing about being hard, hardcore and/or a hardcore gangsta. After all, it's easier to be tough-looking (scowl, wear droopy pants, hold prop gun) than it is to be genuinely funny (rapping about Boba Fettistoo funny). Catch the master of ridiculous rhymes at the Hi-Pointe (1001 McCausland Avenue; 314-781-4716). Tickets are $10, and the Hi-Pointe opens at 5 p.m.; this being hip hop, the show will start later that evening.
