Before squeezing her way to the stage at 512 rooftop bar overlooking Austin, TX's riotous 6th Street Thursday night (Mar. 15), Elizabeth Harper, a/k/a Class Actress managed to make glamorous the dark back alley, where she posed for pre-performance portraits for Idolator. The striking brunette would later slink out of the classic khaki trenchcoat she wore — appropriate for the misting weather — to reveal an oversize black blazer, white chemise, leggings and chunky jewelry. There was more to come off as she cooed through her first SXSW appearance this year, including the pulsating "Weekend" and "Keep You", under pink and purple lights and accompanied by live drums and synth. "This is fun," she told the crowd as she bopped and hair-flipped vintage Madonna-style, and we all agreed.
