Music documentaries to watch out for (they're all screening at Sundance this week):
Everyone Stares, a reputedly exhaustive, detailed history of the Police, directed by Stuart Copeland.
Heart of Gold, about (who else?) Neil Young, and directed by Jonathan Demme.
Awesome: I F---in' Shot That!, a Beastie Boys concert docu, the twist being that the footage was shot by 50 Beastie fans who were handed cameras and told to shoot to their hearts content.
Leonard Cohen I'm Your Man, self-explanatory.
