Just after the US tour ended, the band performed at the Altamont Free Concert at the Altamont Speedway, about east of San Francisco. The Hells Angels biker gang provided security. A fan, Meredith Hunter, was stabbed and beaten to death by the Angels after they realised he was armed. Part of the tour, and the Altamont concert, was documented in Albert and David Maysles' film "Gimme Shelter". In response to the growing popularity of bootleg recordings (in particular "Live'r Than You'll Ever Be", recorded during the 1969 tour), the album "Get Yer Ya-Ya's Out!" was released in 1970. Critic Lester Bangs declared it the best ever live album. It reached No. 1 in the UK and No. 6 in the US.
