Theme :: Altamont. On this day in 1969, the Rolling Stones, Jefferson Airplane, Santana, CSNY, and others held the Altamont Speedway Free Festival. The festival was expected to be a west coast Woodstock. However, with security being handled by the Hells Angels motorcycle gang, the event was marred by violence including one murder and three accidental deaths, in addition to numerous injuries and extensive property damage.
The show was captured in the documentary Gimme Shelter, which I'd highly recommend.
