The Altamont Speedway Free Festival was a counterculture-era rock concert held on Saturday, December 6, 1969, at the Altamont Speedway in northern California, between Tracy and Livermore. The event is best known for considerable violence, including the death of Meredith Hunter and three accidental deaths: two caused by a hit-and-run car accident and one by drowning in an irrigation canal. Four births were reported during the event.
