MSTRKRFT's Jesse Keeler recently explained the title of the techno rockers' new single, "VUVUVU," thusly: "The song was inadvertently named by Xavier [de Rosnay] from Justice. He says the music they make is [imitates] 'PRPRPRPR TISH, PRPRPRPR TISH' and the music we make is 'VUVUVU.'" Indeed, MSTRKRFT's DJ sets keep up a thick, heavy bass pulse more in line with straight techno than with Justice's metal riffs and disco breaks. With LA Riots and Lazaro Casanova.
