You can read about Big Freedia — for example, the 2010 New York Times feature that helped introduce New Orleans’ gender-flouting, booty-bobbling “sissy bounce” phenomenon to the asses of the masses, or in the web’s worth of breathless testimonials that’ve ensued since then as she’s traversed the nation setting untold behinds quivering. You can listen to her music — most recently the God Save the Queen Diva mixtape, which in true gutter-bounce appropriationist style slices up Little Richard, Diana Ross and Freddie Mercury (not a bad triangulation of her onstage persona) plus the Rocky theme (which should play well here) atop relentlessly re-upping stutter-step booty-beats. And you should absolutely watch her videos, particularly last year’s epic “Y’all Get Back Now.” But if you haven’t experienced firsthand the euphorically sweaty spectacle of a Big Freedia show (and, ideally, gotten up to shake what you’ve got yourself), well … you might want to do yourself a favor this Friday night.
