Step into the way-back machine and return to the times of luv, peace, and understanding. Powerful chronicle of the great 1969 Woodstock rock concert celebrates the music and lifestyle of the late '60s. More than 400,000 spectators withstood lack of privacy, bathrooms, parking, and food while wallowing in the mud for four days to catch classic performances by a number of popular performers and groups. Martin Scorcese helped edit the documentary, trail-blazing in its use of split-screen montage. A director's cut is available at 225 minutes.
