Merce Cunningham (1919–2009) was one of the most influential figures in the history of modern dance in America, known in part for his collaborations with legendary composer John Cage and visual artists including Robert Rauschenberg. Director Alla Kovgan used vintage footage, photographs, and recordings of the choreographer and key figures in his life, and newly staged excerpts from 14 of Cunningham’s works—vividly captured with 3D cinematography—for his one-of-a-kind tribute to a modern dance visionary.
