As part of the Movement Without Borders series, PS21 is teaming up with the city of Hudson and local youth and community groups to present a master class with the Mark Morris Dance Group, as part of Waterfront Wednesdays, a summer series of family-friendly programming at Henry Hudson Waterfront Park. This movement workshop introduces the community to choreography from some of the works in the group’s repertoire, taught by Mark Morris Dance Group members, and accompanied by live music. The event is open to the public.
