PARTY DREAM brothers Gil Mantera and the Ultimate Donny wield the cutting edge of electro, synth-pop party soundtracks with a soft-focus image and a white-leather disposition. Their sound is a breezy, dance-floor throwback to the "Miami Vice" decade, cut from a cloth of vibrant, '80s pop beats and over-the-top sex jam crooning that takes shape in a scene of feathered hair, big bass and billowing clouds of smoke-machine ambiance. Guyliner and Sunbears open the show. $10. 9 p.m. The Earl, 488 Flat Shoals Ave. 404-522-3950. www.badearl.com.
