Mr. Quintron is an entertainer and an inventor from New Orleans, a black-magic scientist and organ-grinding nightclub singer, plowing through everything in his path with a two-tier keyboard rig tricked out to look like the grill of an oncoming hearse. With him as always are his patented Drum Buddy, an analog drum machine whose engine is a light bulb and a rotating coffee can, and his better half, Miss Pussycat, a homemade puppeteer and maraca shaker par excellence. With Golden Triangle and TacocaT. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $10 adv/$12 DOS, 21+.)
