Coming to PBS is the American Experience documentary Woodstock: Three Days That Defined A Generation. Brooklyn Vegan posted that the film, which premised last month at The Tribeca Film Festival, will open in select theaters beginning on May 24th and was directed by Barak Goodman, and written by Goodman and Don Kleszy. In celebration of the 1969 festival's 50th anniversary, PBS channels will run the film on August 6th at 9 p.m. ET.

According to the press release: “In August 1969, half a million people from all walks of life journeyed from every corner of the country to a dairy farm in upstate New York for a concert unprecedented in scope and influence. Woodstock examines the tumultuous decade that led to those three historic days — years that saw the nation deeply divided by Vietnam and racial, generational and sexual politics — through the voices of those who were present for the event that would become the defining moment of the counterculture revolution.”

We asked Woodstock organizer Michael Lang at what moment he realized that he was helping to create cultural history: “I guess by Saturday, when everybody had arrived — or anybody who was gonna get there arrived. We knew that this was a historic moment in any case. Whether it resonated or not, nobody thought of that, but we knew that this was extraordinary.”

Pete Townshend still regards the Who's 1969 Woodstock as a watershed event in the band's live career: “It was about the most important single concert that we ever did. It was more important than Monterey, much more important than our first show in New York, much more important than anything that followed.”
