With “Alive,” the third cut and single from “Head First” (Mute, 2010), Allison Goldfrapp plays an aerobics instructor role. So far so good. The plot thickens when the alumnae turn into vampires and drink their male companion’s blood... and there you have it: the story for an eighties horror movie. Mission accomplished. Especially if you take into account that the soundtrack contains the epic electronic disco synths of the decade. “Alive” will be available from 17th June, and features remixes by Dave Audé, Joakim and Arno Cost.
