Rogaine-promoting cover art aside, Robert Babicz’s newest full-length will easily satisfy those who know Babicz better via his Force Inc.- and DJ moniker, Rob Acid. A Cheerful Temper‘s deep, hypnotic minimalism smacks of Cologne’s distinctive techno sound, with dubby tracks like “Imperial Star” reminding us why this imminently danceable style had such an impact in techno music. Standouts include the swooping, pummeling bass on “Sin” and the clicky-textured “Losing Memories,” which faintly recalls Babicz’s work as Atlon Inc. The exceptional “Chrystal Castle” shows this veteran producer’s love of old-school Detroit, retrofitting his groove with funk-steeped analog rhythms from a warehouse dancefloor long, long ago.
