Altamont is a speedway in Northern California, near Tracy, that hosted a rock music festival in October 1969. The festival included the Rolling Stones and other bands (including the Grateful Dead and the Jefferson Airplane) after a previous venue proved to be too small. The small stage was surrounded by Hells Angels who acted as bouncers. The crowd management proved to be a disaster and many people were hurt and one man killed. The news agencies reported the event as a "drug induced riot." The Altamont concert is often contrasted to the Woodstock festival earlier in 1969, sometimes being said to mark the end of the innocence embodied in Woodstock.
