Film and music of shimmering yet jarring beauty play together on a South Seas beach in “Legong: Dance of the Virgins.” It’s a rarely screened 1935 silent movie, shot entirely in Bali with a Balinese cast, mixed with a new score by Club Foot Orchestra and Gamelan Sekar Jaya. Presented in a crude but rich two-strip early Technicolor process, one of the last silent films made by Hollywood, it depicts Bali as Westerners idealized it at the time.
