Cappella Romana, a vocal chamber ensemble renowned for its ''robust and intriguing music'' (Washington Post), releases its latest recording ''Live in Greece.'' Its previous release ''Music of Byzantium'' sold over 14,000 copies. A 1000-year journey from Constantinople to California, ancient Byzantine chants are 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, continued by his Californian peers of Greek-American choral music.
