"Woodstock," the concert, gave voice to the spirit of a generation, offering the world a three-day microcosm of the turbulent '60s, set to the music of the era's greatest rock performers. "Woodstock," the film, captures it all, now with more than 40 minutes of added material and masterfully remixed sound. This Academy Award-winner for Best Documentary Feature shows in spectacular detail how and why the legendary "Summer of Love" festival was an historical event, and now features additional interviews, memorable footage and, of course, more of the music that brought this "happening" together. This ground-breaking documentary also offered an early career boost to a young Martin Scorsese ("GoodFellas," "The Aviator"), who served as an editor and assistant director. In 1996, the film was inducted into the Library of Congress National Film Registry.
