The members of Arcade Fire are big nerds with good taste, so it shouldn’t surprise anyone that they’re Devo fans. At last year’s Crossing Brooklyn Ferry festival, four Arcade Fire members, performing under the name Phi Slamma Jamma, got together to cover “Uncontrollable Urge,” a song from Devo’s 1978 debut Q: Are We Not Men? A: We Are Devo! And last night, Arcade Fire played a show at L.A.’s Hollywood Palladium, and they busted out a full-band cover of the same song, played while Win Butler was wearing one of those gigantic waxy masks. But if you’re going to cover Devo on Halloween, I don’t know how you do it without forcing the entire band to wear lobotomy flowerpots. Check out a fan-made video below.
