Popmatters.com has an excellent review of Robert Elfstrom’s documentary Johnny Cash: The Man, His World, and His Music (1969). The film highlights Cash at his career pinnacle and looks back at his upbringing in rural
Arkansas.From the review: More than that, he was content to dwell in contradiction; he didn’t try to resolve all his warring selves. He was equally the outsider rockabilly and the establishment patriot, the social protestor and the Billy Graham crusader. He gave us a model of cultural ambivalence that we could all identify with. He didn’t solve America’s identity problems, he showed us how to live with them.
