Check out the list of the best rock documentaries of all-time compiled by the readers of "Rolling Stone" magazine. One of my favorites "The Last Waltz," by Martin Scorsese a film dealing with the final concert by The Band, is number one on the list. "Woodstock" came in second. Rob Reiner's mockumentary "This Is Spinal Tap" — was third on the list. The Rolling Stones' "Gimme Shelter" and Pearl Jam's "Twenty" were at fourth and fifth.
