The Grateful Dead performing at Woodstock, photographed from behind the stage by Elliott Landy, the photographer who can walk through walls. Jerry Garcia said that the Woodstock performance was the worst of the band's career. Maybe it was because they were standing in a puddle of water on a flooded stage, and he was getting shocked through his fingertips. Now that would be weird. Photo courtesy of Landyvision.
