The three-day Woodstock music festival in 1969 was the pivotal event of the 1960s peace movement, and this landmark concert film is the definitive record of that milestone of rock & roll history. It’s more than a chronicle of the hippie movement, however; this is a film of genuine historical and social importance, capturing the spirit of America in transition, when the Vietnam War was at its peak and antiwar protest was fully expressed through the liberating music of the time. With a brilliant crew at his disposal (including a young editor named Martin Scorsese), director Michael Wadleigh worked with over 300 hours of footage to create his original 225-minute director’s cut, which was cut by 40 minutes for the film’s release in 1970.
