What makes this 2012 documentary about the Rolling Stones so interesting has little to do with the newly recorded material – the Stones even demanded that only their voices be used, not their faces, as though they were in some sort of rock star witness protection program. But the vintage film, captured at their first gigs and showing the increasing sort of mania they produced at their concerts and club showings, is a riot. Often literally. And while Beatlemania generally stirred young preteen girls into a frenzy, with the Stones, just as often, it was the rowdy young boys, looking for a fight, and usually finding one. Usually with the cops.
