For three days in the summer of 1969, a rock concert was held on an upstate New York farm, and 400,000 people attended -- far more than were anticipated, far more than paid, far more than could be fed or sheltered or cared for after injuries or drug overdoses. It rained, there was mud, all traffic in and out was gridlocked, and the music continued, night and day. "Woodstock Nation" existed for three days and was absorbed into American myth. As depicted in this film, in roughly chronological order, the elusive memory of that nation is cemented into a pungent social documentary. Few documentaries have captured a time and place more completely--in the full flower of its moment, youth, and hope--than this one. It is also one of the finest musical documentaries ever made--if not the best--utilizing adventurous camera work, daring editing, frame mirroring, freeze frames, blackouts, and multi-angle perspectives widening the 1.33:1 image to 2.20:1 to capture flamboyant, riveting, career-defining performances, within an amazing chronicle of how the musicians interact onstage as audience members react to the musicians' performances.
