What does a baby's cry have in common with the echo of a mountain yodler, and what connects the head tone of a Tuvin nomad with the stage show of a vocal artist? The answer is: THE VOICE.

Their universe of sound extends far beyond what we would describe as singing. In their engagement with local and foreign traditions, the powerful mountain landscape becomes a stage as do the landscapes and sonic backdrops of modern life.
