In 1956 Robbins' muse, Tanaquil LeClercq, contracted polio and was paralyzed; for the next decade Robbins largely withdrew from his activities at New York City Ballet, but he established his own small dance company, Ballets USA, which premiered at the inaugural season of Gian Carlo Menotti's Festival of the Two Worlds in Spoleto, Italy in June 1958, toured Europe and the US under the auspices of the State Department, and appeared on television on The Ed Sullivan Show. Among the dances he created for Ballets USA were N.Y. Export: Opus Jazz and Moves.
