Black Devil in Dub is a Janus-faced piece of decadent tech-disco, split between originals and outsider remixes of the same material. French producer Bernard Fevre, the driving force behind Black Disco, has put out only three releases. Two have come in as many years previous but his debut, the Disco Club EP, dropped back in 1978. That lengthy gap in time is reflected in his latest’s deliberate disunity of style. Fevre’s sound — thin, shiny, and overly streamlined — fluently evokes yesteryear but struggles to shake off its schematic, autopiloted feel. In contrast, the remixes conducted by such Euro-acts as Elitechnique, Quiet Village, and In Flagranti unfold pregnant with propulsive mystery and are messier and denser. Ultimately, Dub is all sleazily synthetic, uber-hopped up electronic that exists to keep bodies in sweatily gyrating motion. And, past or present, this is no challenging aim.
