Mr. Yauch once said that the Beasties had started rapping as a joke, but found that audiences liked it better than their punk-rock. In 1994 Mr. Yauch started the nonprofit Milarepa Fund, which presented the Tibetan Freedom Concert series to raise awareness of Chinese control of Tibet. Mr. Yauch moved into film distribution and production with Oscilloscope Laboratories, operating it like an independent record label where everything was done in-house. Oscilloscope’s first releases, small indie films and documentaries, were modest in critical reception and box office, but the company quickly scaled up. In 2009 Oscilloscope drew recognition for Oren Moverman’s military drama “The Messenger,” including Oscar nominations for best original screenplay and best supporting actor (Woody Harrelson). Another Oscar nomination, for the documentary “Exit Through the Gift Shop,” followed. In 1998 he married Dechen Wangdu, who survives him along with their daughter, Tenzin Losel; and his parents, Frances and Noel Yauch.
