The Woodstock Music &amp; Art Fair was a music festival held on a 600-acre (2.4 km2; 240 ha, 0.94 mi2) dairy farm in the rural town of Bethel, New York, from August 15 to August 18, 1969. Thirty-two acts performed during the sometimes rainy weekend in front of nearly half a million concertgoers. It is widely regarded as one of the greatest moments in popular music history and was listed on "Rolling Stone"s "50 Moments That Changed the History of Rock and Roll".
