No choreographer alive has a higher reputation for musicality than Mark Morris; and that reputation — despite several blunders along the way — has been well earned over more than 30 years of marvelously eclectic creativity. From the Baroque to American modernism, from Monteverdi to Stravinsky, from Stephen Foster to jazz, his dances have brought music to meet dance in ways that have expanded our appreciation of the alchemy that these two arts can achieve together. And he is singularly, courageously, committed to live music in a field where, for economic reasons, recordings are increasingly employed.
