The Muom Overtone Singing Choir Explore Vast, Rapturous Sonic Expanses

Few choral groups explore such a vast expanse of sound as the Muom Overtone Singing Choir. Their extended technique is breathtaking in the purest sense of the word. Neither the sepulchrally wispy highs nor the stygian lows they often reach at the same time exist in most music for the human voice, simply because most people can’t hit those notes. The ensemble’s magical new suite Terra – streaming at Bandcamp – is the first in a planned series of four. The late Maurice White would be delighted to know that the next two are explorations of wind and fire, water being the fourth element.

The suite, performed as a contiguous whole, begins with Eter, a single D note sung in unison until some of the choir reach a couple of octaves lower for a guttural anchor. By this point, harmonics are oscillating in the background. From there the group segue into Astral, slowly coalescing into an aptly drifting theme with gentle massed glissandos and long, sustained notes moving through the sonic picture, a graceful deep-space exchange of voices. Rhythm falls away to a cocooning, enveloping, uneasy morass, then the counterpoint rises again.

The group completely flip the script with Ardhi (Swahili for “earth”), with a joyously cantering, percussive west African groove, mens’ lows and spiraling overtones against the triumphant women overhead. They whisper their way out.

There’s a return to rapt, otherworldly stillness in Akasha (Sanskrit for “ether”). The men in the choir open Sa Mantra (sa being Tibetan for “earth”) with a low, growling chant, riffing on a phrase common to carnatic music and vocal warmup exercises. From there, they build a starkly bluesy minor-key theme.

A plaintively expressive solo by one of the men, like a muezzin’s call, takes front and center over allusively chromatic phrasing in the next segment, Ancestral, before the ensemble kick into a rousing, insistently rhythmic drive. Khörzün (“earth” in the Tuvan language) is where Central Asian choral traditions resonate the most here, via echoing layers of harmonics and a galloping trans-Siberian beat.

The choir close with Gea (the Greek earth deity), a starkly circling violin solo by group member Farran Sylvan James introducing a hypnotic downward drift. There hasn’t been any album like this released in the recent past, maybe ever, reason to look forward to whatever other magic the group can conjure in the next installment.
