Billed as "An Aquarian Exposition: 3 Days of Peace & Music," the Woodstock Festival was held at Max Yasgur's 600-acre dairy farm near White Lake in Bethel, New York, 43 miles (70 km) southwest of Woodstock. Over the sometimes rainy weekend, 32 acts performed outdoors. It is widely regarded as a pivotal moment in popular music history, as well as the definitive nexus for the larger counterculture generation. Rolling Stone listed it as one of the 50 Moments That Changed the History of Rock and Roll. Joni Mitchell described the legendary event as "a spark of beauty" where half-a-million kids "saw that they were part of a greater organism". In 2017, the festival site was listed on the National Register of Historic Places.
