...They Were Half A Million Strong
Why did more than 400,000 young people trek across the country in 1969 to hear a music festival in the middle of nowhere? A new PBS documentary, “Woodstock: Three Days That Defined a Generation,” looks at the legendary music festival through the eyes of its attendees — young people looking to escape the anxieties of the late '60s. Woodstock took place during the height of the Vietnam War, a week after the Manson murders and a month following Neil Armstrong’s moon landing. Barak Goodman, the director and co-writer of the film, spoke with John Horn about how the festival came together and why it almost failed. (The film has a limited theatrical release on June 7.)
