Hip Glossary – Altamont:

Altamont:: Controversial, ill fated rock concert headlined by the Rolling Stones and Jefferson Airplane at Altamont Speedway on Dec.24, 1969. Hells Angels, acting as security, had their hands full as people kept rushing the stage. One man pulled a gun, and the Angels killed him. The film “Gimme Shelter” documenting the concert was used in evidence to clear the Angels.
