The song features the vocals of classically trained singer Aerea Negrot who has been dubbed "the Eartha Kitt of the techno age." Butler told Pitchfork
about her: "She's born Venezuelan, lived in Berlin for six years. She's a classically trained singer, but her voice is just ridiculous. It spans numerous octaves, and she evokes some of the classic, classic singers-- female divas from even pre-disco times. Her hero is Yma Sumac. She's a very Latin big-voiced kind of lady, but what she's done for me sounds like I have one of the best, most ferocious disco vocalists from the 70s appearing on a record, which is really f---ing cool. She's a solo artist, as well. She's in the works as well with the label BPitch Control, a Berlin techno label. Her own thing is very experimental, very improvisational, and very performance-oriented."
