Shock in Altamont
The Altamont Free Concert, initiated by the Stones management, was intended as a peaceful counter event to Woodstock. Alongside the Stones on stage were, among others, Santana, Crosby, Stills, Nash & Young, and Jefferson Airplane. When the Stones appeared, there was a great deal upheaval among the audience and the concert needed to be interrupted. The Hells Angels were behind the commotion.
