The New York City Ballet performed at the opening ceremony for the Saratoga Performing Arts Center in 1966 and returns each year for their summer residency. The 60th summer residency runs from July 8-11 and we spoke about the season with the Artistic Director (and former principal dancer) of the NYCB, Jonathan Stafford.
