'Those days were unlike any our generation had even heard of before, much less experience' - former Rolling Stone photographer Robert Altman

As one of the lead Rolling Stone photographers in late sixties and seventies, Robert Altman's candid shots captured the luminaries of every sphere of influence, from politics and music through to the disciples of free love, creating a unique photographic journey through the era. Now, 60 of Altman's images are to be displayed at the Idea Generation Gallery in London, England in an exhibition billed as The Sixties.

Comments Altman, "I knew what I was capturing was historically important. Even though we were not part of the 'Establishment' we knew that our generation was 'rocking' the world.

"Part of the magic of the sixties was that we knew there were thousands and thousands, perhaps millions, of us spread beyond the United States and all across the world," he says. "I absolutely knew that this was something different and something very special. Those days were unlike any our generation had even heard of before, much less experience."

The Sixties, photographs by Robert Altman, will be at the Idea Generation Gallery from July 15 to Aug. 29. Located 11 Chance Street, London E2, 020 7749 6851. Free admission. The Sixties, edited by Ben Fong-Torres, is available from Santa Monica Press.
