Best known as the key members of the San Francisco-based Soulstice, Gina Rene and DJ Mei Lwun also share a love of improvisational music. Their unrelenting electronica is laced with breakbeats and sultry vocals -- and will keep you partying till the sun comes up. The turntablist-singer combo circumvents genre labeling with an innovative freestyle approach that delights the refined ear while keeping the crowd moving. Lightweights beware: When the two women perform for the late-night crowd at Enigma Afterhours on Friday, August 16, the fun doesn't even start until 1 a.m. But why sleep when you can have an audience with two queens of clubland?
