Woodstock

The Woodstock Music and Art Fair was a historic event held at Max Yasgur's 600 acre (2.4 km²; 240 ha) dairy farm in the rural town of Bethel, New York from August 15 to August 18, 1969. Bethel (Sullivan County) is 43 miles (69 km) southwest of the town of Woodstock, New York, which is in adjoining Ulster County.
To many, the festival exemplified the counterculture of the 1960s and the "hippie era." Thirty-two of the best-known musicians of the day appeared during the sometimes rainy weekend. Although attempts have been made over the years to recreate the festival, the original event has proven to be unique and legendary. It is widely regarded as one of the greatest moments in music history and was listed on Rolling Stone's 50 Moments That Changed the History of Rock and Roll .
The event was captured in a successful 1970 movie, Woodstock, and Joni Mitchell's song "Woodstock," which commemorated the event and became a major hit for Crosby, Stills, Nash & Young.

Woodstock '94 was a music festival organized in order to commemorate the 25th anniversary of the original Woodstock Festival of 1969. It was promoted as "2 More Days of Peace and Music." The famous poster used to promote the first concert was revised to feature two birds perched on a guitar (instead of one).
The concert was scheduled for August 13, 1994 and August 14, but a third day (August 12) was added.
