Within four bars of its clacky, syncopated opening, “Cluerman” by Nashen off the free, three-track Source EP has registered as a keeper. Even when the minimal techno trappings — serene wooshes, clubby counterpoint, machine gurgles — risk layering in too much for the whole to truly register as minimal, it has a trenchant, single-minded purpose that’s admirable (MP3). Ditto the echo-laden “Zinkin” (MP3) and the more mechanistic “Hating You,” the latter of which ditches any appearance of analog source material in favor of a machine dream (MP3).
