The Beat: Elle Women in Music

Talk about girl power. The fifth annual Elle Women in Music celebration at Los Angeles' historic Avalon Hollywood, moderated by the magazine's editor-in-chief Robbie Myers, played host to a number of private performances for the invite-only crowd. Betty Who high-kicked her way through a lively set, Angel Haze performed a mix of rap and acoustic covers, and Sarah McLachlan captivated the audience with songs from her new album, "Shine On," as well as such favorites as "Adia" and "Ice Cream." The bash, which treated guests to a Dior makeup station and gourmet eats of fried risotto and beef sliders, also drew AlunaGeorge's Aluna Francis; Sophia Bush in a Camilla and Marc skirt; and Rumer Willis, who rocked a black cut-out Franziska Fox dress and hit the turntables after the performances.
