It can be hard to make time in one’s life for modular synthesizer music. Why listen to long, drifting drones when it’s possible to just dial up something with a tasty beat, a nice jam or a hook that demands to be played over and over? M. Geddes Gengras’ Ishi contains the answers, and there are multitudes. They come spelled out in cumulus formations that gather into thunderheads and break into cleansing bit-rains (“Passage”) and through luminous stereo waveforms, collecting and dispersing through the mind’s ear (“Threshold”). It’s easy enough—and sometimes even helpful—to cloak synth jams in New Age mumbo-jumbo, but—on good headphones—albums like Ishi are like cloud-watching, stargazing and lucid dreaming rolled into one.
