In August 1969-against a backdrop of a nation in conflict over sexual politics, civil rights, and the Vietnam War-half a million people converged on a small dairy farm in upstate New York to hear the concert of a lifetime.

What they experienced was a moment that would spark a cultural revolution, changing many of them and the country forever. With never-before-seen footage, WOODSTOCK: THREE DAYS THAT DEFINED A GENERATION tells the story of the political and social upheaval leading up to those three historic days, as well as the extraordinary events of the concert itself, when near disaster put the ideals of the counterculture to the test.
