The Woodstock music festival was planned for 50,000 people in upstate New York, but attracted 10 times that on a rain-plagued weekend in August 1969, clogging traffic and taxing the local infrastructure. Yet, the event became a marvel of peaceful coexistence and a symbol of Sixties’ communal values. The music, by Crosby, Stills and Nash, Country Joe MacDonald, Richie Havens, Joan Baez, Arlo Guthrie, the Who, Jefferson Airplane, Santana, Joe Cocker, Grateful Dead, Jimi Hendrix, Creedence and others, became the soundtrack of a generation. The PinkSlip Duo will play much of that music and tell the story of that momentous event, with narration and slides.
