In August 1969, nearly half a million people gathered at a farm in upstate New York to hear music. What happened over the next three days, however, was far more than a concert. It would become a legendary event - one that would define a generation and mark the end of one of the most turbulent decades in modern history. Occurring just weeks after an American set foot on the moon, the Woodstock music festival took place against a backdrop of a nation in conflict over sexual politics, civil rights, and the Vietnam War. A sense of an America in transition - a handoff of the country between generations with far different values and ideals - was tangibly present at what promoters billed as an Aquarian Exposition: 3 Days of Peace and Music.
