Island Moving Company brings back its annual Great Friends Dance Festival for another year. Each July, the ballet company invites a guest group to Newport for two weeks of public studio and performance time, in exchange for a reciprocal visit by the Newport dancers the following spring. This year’s resident company is Owen/Cox of Kansas City. Each night’s program changes over the course of the festival, and each begins with an étude choreographed that very day with dancers from both companies. They’ll also be joined by other groups, including Nomad Contemporary Ballet from New York and Providence’s part of the oath.
