Prinzhorn Dance School, Home Economics. These six deceptively laid-back dark-pop experiments are positively mesmerizing. They take their time, but don’t meander, using repetition and rhythm to slowly gather steam and get to the point. The songs are like little dancefloor dramas. The style will appeal to fans of Brit post-pop bands like Gang of Four and Shriekback, but this is a calmer, less complicated variation. Most of the tracks have one-word titles (“Reign,” “Clean,” “Haggle”) but not one-track minds. Even the dance tracks have suspense and menace in them.
