Leap into Spring will feature George Balanchine’s Concerto Barocco. One of Balanchine’s greatest masterpieces, Concerto Barocco is music made visible as two elegant yet dynamic lead ballerinas each depict one of the instrumental soloists in a virtuosic double violin concerto. It is considered the quintessential Balanchine ballet of its period, its manner entirely pure, its choreography no more, and no less, than an ideal response to its score, Bach's Double Violin Concerto in D Minor.
