Harkness Dance Festival

92Y marks the 100th anniversary of the birth of dance innovator Merce Cunningham with a month of performance and visual arts. The opening weekend is devoted to Cunningham dances performed by New York Theatre Ballet, New World School of the Arts, Melissa Toogood and Calvin Royal III. Subsequent weeks offer world premieres by companies founded by erstwhile Cunningham dancers: Douglas Dunn, Dylan Crossman, Jonah Bokaer and Ellen Cornfield. (James Klosty’s photographs of the Cunningham company are on view at 92Y through April 2.)
