Who: The brothers Lawrence, who caught the ear of dance music fans with 2012 tracks "Latch" and "Tenderly/Flow," parlayed that success into 2013's breakthrough album Settle. The open arrangements and stuttering rhythms on the U.K. chart-topper pushed the LP to Number Two on Rolling Stone's list of the year's best dance albums.
Why You Can't Miss Them: This February, right when it seemed like duo couldn't get any more mileage from their LP, Mary J. Blige contributed verses and vocals to "F for You," adding some early-Nineties New York garage-soul to their early-Aughts U.K. garage bounce. As Blige reminded us, playing the record remains the easiest way to get a group of young people moving in place. For example, the duo's closing set at last year's festival was so energetic that fans attempted to jump the barricades separating the audience from the stage. This year expect extra security.
