A killer hook … offbeat pop-culture references … diva shout-outs … hot trannies … and fast food! NYC clubutante Cazwell’s infectious dance jam and its accompanying video, “I Seen Beyonce at Burger King,” has all the makings of a viral Web sensation, but make no mistake, the homo-hip-hopper is more than another YouTube fame whore, and he’s no novice. In New York, Caz rolls and records with the likes of trashtastic duo Avenue D and Barbie-esque boy-toy Amanda Lepore, and he’s graced every gay rag in town. His ode to the Bootylicious One’s eating habits aside, Caz’s kooky club bangers are infectious even when they’re not purely schticky/dicky, and his appearance at Mustache Mondays is sure to be a Whopper in more ways than one. The ’Stache, by the way, has moved once again, from the basement of 740 to La Cita (previous parties took place at Crash Mansion and Charlie O’s), but this dance party’s a blast no matter where the manscape. Cazwell, plus Leopold & The Bang Bang Bang and DJ Josh Peace, Mustache Mondays at La Cita, 366 S. Hill St., dwntwn.; Mon., Aug. 25, 10 p.m.-2 a.m.; over 21; $5. www.mustachemondays.com.
