San Francisco Ballet's final program of the season, "Program 8," honors groundbreaking choreographers and composers of the 20th century with a triple bill of works by George Balanchine and Jerome Robbins to music by Igor Stravinsky, Philip Glass, and Johannes Brahms as orchestrated by Arnold Schoenberg. Crowning the program is Balanchine's iconic neoclassical ballet Agon. First staged in 1957, the ballet dressed its dancers in leotards and tights and thrilled audiences with its stark attack and abstract humor, all to Stravinsky's twelve-tone adaptations of 17th century French court dances. Brahms-Schoenberg Quartet, a rarely-seen ballet, is a history of the form in four movements that range from classical to romantic to neoclassical to an unrestrained melee of dance. Last but not least, Robbins' Glass Pieces is a salute to the bustle of the city, offering glimpses of the small, rare moments of human connection within the ceaseless barrage of urban activity.
