“Upaj: Improvise” follows two dance masters—Indian Kathak guru Pandit Chitresh Das and African-American tap star Jason Samuels Smith—as they join forces for an extraordinary artistic collaboration, “India Jazz Suites.” Though they are from two different worlds, the two share a special bond, a desire to preserve their dance traditions. Directed by Hoku Uchiyama, the film is co-presented by the Center for Asian American Media.
