Ancient Byzantine chants begin this 1,000-year journey from Constantinople to California, followed by musical encounters with Crusaders and Venetians, including Greek and Latin polyphony from Renaissance Crete. East meets West again at St. Sophia Cathedral in Los Angeles, where Frank Desby founded a tradition of Greek-American choral music with his Californian colleagues. The tour comes full circle with the mystical ecstasy of Radiant Cloud, a sonic icon of the Transfiguration by Athenian composer Michael Adamis.
