Vocalist, composer, and overtone-singing pioneer David Hykes joins us on this New Sounds to preview new works for harmonic singing. Hykes has a long immersion in Eastern and Western sacred music, cosmology, and yogas of sound. He was the first westerner to connect deeply with the "throat-singing" traditions of Mongolia, Tuva and Tibet, and employ overtones which govern all spatial and mathematical relationships. And as always, much more.
