Apollo, a dance depicting the Greek god’s interaction with his muses, is the oldest Balanchine ballet in the repertory, created in 1928 in Paris. The dance marked the first significant collaboration between the choreographer and Igor Stravinsky, arguably his greatest musical muse. La Sonnambula, with its atmospheric sets and costumes, spins forth a mysterious dramatic world in its depiction of the sleepwalker of the title and the poet whom she bewitches, with tragic consequences. Completing the program is Tschaikovsky Piano Concerto No. 2, one of Balanchine’s most resplendently beautiful homages to the grand classical tradition.
