On April 5, 6 and 7, 2013, a quartet of internationally renowned composer-improvisers – Mark Dresser, Nicole Mitchell, Myra Melford and Michael Dessen – performed an unprecedented “virtual tour” of new music conceived for world-class improvisers performing together in different geographical locations via Internet2. Taking advantage of high bandwidth networks available only at research and educational institutions, these concerts featured virtuoso performers performing together across thousands of miles with lifelike, uncompressed audio and minimal time delays and HD video, setting a new standard for music making on the telematic stage.
