The Altamont Speedway Free Festival was a counterculture rock concert in 1969 in the United States, held at the Altamont Speedway in northern California on Saturday, December 6. The event is best known for considerable violence, including the stabbing death of Meredith Hunter and three accidental deaths: two caused by a hit-and-run car accident, and one by LSD-induced drowning in an irrigation canal. Scores were injured, numerous cars were stolen and then abandoned, and there was extensive property damage
