For three days in August 1969, nearly a half-million young people descended upon Max Yasgur’s farm in upstate New York for the rock ‘n’ roll event that defined a generation. Mythologized for 50 years, the filmmakers set the record straight with “Creating Woodstock,” the most comprehensive examination of how the festival came to be.

An intimate look at the Woodstock Music & Art Festival held in Bethel, NY in 1969, from preparation through cleanup, with historic access to insiders, blistering concert footage, and portraits of the concertgoers; negative and positive aspects are shown, from drug use by performers to naked fans sliding in the mud, from the collapse of the fences by the unexpected hordes to the surreal arrival of National Guard helicopters with food and medical assistance for the impromptu city of 500,000.
