Woodstock - 3 Days of Peace & Music (1970)

In director Michael Wadleigh's innovative, documentary-style epic (originally X-rated due to brief glimpses of nudity) about the upper-state New York rock-music concert held on Yasgur's farm in the summer of 1969, exhibiting a revolutionary love generation spirit:

• various memorable performances on stage (Joan Baez, Joe Cocker, Jimi Hendrix playing the "Star Spangled Banner", Richie Havens, The Who, etc.)
• the rain-soaked chaotic denouement
