There’s something very eco-friendly about ‘My Number,’ from Foals. The second cut from their forthcoming album, Holy Fire, feels like a slice of retro-funk which has been upcycled. That restyles the sound of Wild Cherry into the danceable yet intelligent indie for which Foals are famed. The indifference with which Yannis sings the opening lines, “You don’t have my number / We don’t need each other now,” sets the tone for the rest of the band vocals. Who follow his cue and layer their voices in an equally disinterested manner. The result is brilliantly modern; a morose funk that hipsters can dance to with the cool detachment they prize.
