The daylong gala event culminates in an 8:30 p.m. concert at the Koussevitzky Music Shed featuring the Boston Symphony, the Boston Pops, and the Tanglewood Music Center Orchestra, an ensemble of student musicians.
James Levine, partway through his first Tanglewood season as BSO music director, will lead the orchestra in Berlioz's Roman Carnival. Seiji Ozawa, Levine's predecessor, will return to conduct the Tanglewood Music Center Orchestra in Beethoven's Leonore Overture No. 3.
John Williams, the film composer and onetime conductor of the Boston Pops, will lead the Pops in music from his score for Star Wars, while Bruce Hangen, the Pops' current principal guest conductor, will conduct the Symphonic Dances from Bernstein's West Side Story. (Pops chief conductor Keith Lockhart is currently conducting the Utah Symphony, of which he is music director, at the Deer Valley Music Festival.)
Finally, Hans Graf, music director of the Houston Symphony, will end the evening with a performance of Tchaikovsky's 1812 Overture, complete with cannons and fireworks.
