James Levine is an American orchestral pianist and conductor and most well known as the music director of the Metropolitan Opera in New York. He is also the current music director of the Boston Symphony Orchestra.
Levine made his Metropolitan Opera debut in June 1971 in a festival performance of ?Tosca?. His success led to further appearances and to his appointment as its principal conductor in 1973. He then became Music Director in 1976 and later Artistic Director in 1986.
At the Met, Levine has led numerous new productions of works of Mozart, Verdi, Wagner, Strauss, Rossini, Schoenberg, Stravinsky, Kurt Weill, Claude Debussy, Alban Berg, and George Gershwin. For the 25th anniversary of his Met debut, Levine conducted the world premiere of John Harbison’s ?The Great Gatsby?, commissioned especially to mark the occasion.
In October 2004, Levine took the helm of the Boston Symphony Orchestra (BSO), succeeding Seiji Ozawa as music director, and becoming the first American to head the BSO.
