Vermont’s Greg Davis further ditches his rep as a twee laptop-folkie and crafts deceptively simple synth dirges to sneak into your subconscious. On the first track, “Cosmic Mudra,” he takes a grinding chord and builds it for nearly half an hour, from near-silence to searing, cathedral mass-awakening blare. The following “Hall of Pure Bliss” achieves what so many minimalists have painstakingly chased for decades, as the track is little more than a chord that gently rises and falls down in pitch for 22 minutes, melting the listener’s cortex to near-narcotic effect. In times when so much abstract electronic music seems exhausted and lost about where to go next, Davis is already moving into the next decade.
