Woodstock was a music festival, billed as "An Aquarian Exposition: 3 Days of Peace & Music" from 8/15-8/18/1969. During the sometimes rainy weekend, 32 acts performed outdoors before an audience of 400,000 young people. It is widely regarded as a pivotal moment in popular music history. Rolling Stone listed it as one of the 50 Moments That Changed the History of Rock and Roll. It was held at Max Yasgur's 600-acre dairy farm in the Catskills near the hamlet of White Lake in Bethel, NY.
