#7. Gimme Shelter (1970)
It’s part concert film, part rockumentary and part CSI episode. This Maysles’ film about the Rolling Stones takes on a surreal quality as we watch the members of the band watch parts of the film themselves. Most gripping is the final show at 1969′s Altamont Free Concert, in which Mick Jagger was unable to corral the guardian Hells Angels from killing one of the audience. Riveting stuff.
