Michael Lang, co-creator of the Woodstock Music & Art Fair, died on Saturday at the age of 77.

"Woodstock was a test of whether people of our generation really believed in one another and the world we were struggling to create," Lang wrote in his 2009 book The Road to Woodstock. "How would we do when we were in charge? Could we live as the peaceful community we envisioned? I'd hoped we could."
