There's a reason Big Mammas House of Burlesque's latest themed show is Sci-Fi Burlesque Fantasy. Not only is the genre one of the most bizarre, but it's heroes and, more importantly, heroines are usually steaming hot. In skintight attire or hardly any at all, they make us want to live in a galaxy bombarded with evil monsters and invading aliens. This Saturday, Visulite Theatre becomes a futuristic frontier with burlesque from Big Mamma D and an entourage of other lustworthy ladies — both local and regional (White Lightnin Burlesque will journey from the depths of Knoxville, Tenn.) — dressed as your favorite characters (think Princess Leia in a bikini). Other guests, including comedian Johnny Millwater, will also perform. Wear your favorite Sci-Fi fantasy costume for a chance to win a Big Mammas Prize Pack — we don't know what's inside, but it must be good. $12 in advance; $15 at the door. 9 p.m. Visulite Theatre, 1615 Elizabeth Ave. 704-358-9200. www.visulite.com.
