We connected with three professors in Ohio State's Department of Dance for a uniquely informed introduction to the work of legendary choreographer Merce Cunningham: David Covey, Karen Eliot, and Daniel Roberts, all of whom have been members of the Merce Cunningham Dance Company. Alla Kovgan's 3D documentary CUNNINGHAM screens January 24-26 at the Wexner Center for the Arts.
