Cocksucker Blues is an unreleased documentary film directed by Robert Frank chronicling The Rolling Stones North American tour in 1972 in support of their album Exile on Main Street. There was much anticipation for the bands arrival, with their having not visited the United States since the 1969 disaster at Altamont Free Concert, in which a fan, Meredith Hunter, was stabbed and beaten to death by Hells Angels. Behind the scenes, the tour embodied debauchery, lewdness and hedonism. en.wikipedia.org
