Answer
Igor Stravinsky and George Balanchine were two of the most influential figures in 20th century art. They first met in Paris in 1925, and quickly developed a close friendship and working relationship. Balanchine choreographed several ballets to Stravinsky's music, including "The Rite of Spring", "Apollo", and "Agon". Stravinsky also wrote music for Balanchine's ballets, including "Orpheus", "Jewels", and "A Midsummer Night's Dream".
