In just over a decade, The Suzanne Farrell Ballet has evolved from an educational program of the Kennedy Center to a highly lauded company. One of Balanchine’s most famous muses, Farrell herself danced at the Pillow in 1976, performing two Balanchine pas de deux with Peter Martins. Her present company boasts a repertory of more than fifty works, including such rarities as the duet seen here, a light-hearted excursion into Balanchine’s easygoing, hip-swaying American soul. The music was composed for the great Benny Goodman, who performed the solo part at the ballet’s 1964 premiere. This section of the ballet, known as the Contrapuntal Blues pas de deux, was originally danced by Suzanne Farrell and Anthony Blum, and it was restaged as part of the company’s Balanchine Preservation Initiative.
