Leslie Hall, aka Mother Gem, is the gold-plated sexual dynamo at the front and center of LESLIE AND THE LYS, the pride of Ames, Iowa. With a collection of gem sweaters and homespun beats, she raps about everything from slaying zombies to rocking a set of bad-ass shoulder pads to the magnitude of her lady rap dynasty. She's part Dan Deacon, part Har Mar Superstar – bedazzled in sweat and glitter. Stomp once to hear Britney/And twice for Beyoncé/Now three times if you wanna hear Ms. Leslie get nasty. Pleasure Cruise, Christopher the Conquered and Danger Woman warm up the stage for her. $10-$12. 8:30 p.m. The Earl, 488 Flat Shoals Ave. 404-522-3950. www.badearl.com.
