Thom Yorke, Damien Rice and Philip Glass have composed songs for a documentary film about Tibet.

The Radiohead frontman has written three songs for "When The Dragon Swallowed the Sun," a film about the Free Tibet movement's ongoing struggle to gain autonomy from Chinese rule.

Director Dirk Simon has spent seven years making the film, which features HD footage from India, China and Tibet and interviews with Richard Gere, Archbishop Desmond Tutu and the Dalai Lama.

The composers for the documentary's soundtrack were confirmed on the official Web site, whenthedragon.com, which does not confirm a release date but simply says the film is "coming soon."
