The festival was held between August 26 and August 31. It was recognized as the largest musical event of its time, having a greater attendance than Woodstock. The Guinness Book of Records estimates that as many as 700,000 people attended.
That weekend, Supertramp, The Doors, Joan Baez, Joni Mitchell, Miles Davis, Jethro Tull, Emerson, Lake and Palmer, The Who, Sly and the Family Stone, The Moody Blues, Chicago, Jimi Hendrix and Leonard Cohen were among the many musicians to take the stage.
The vast turnout resulted in events such as this being banned for another thirty-two years.
