Iggy Pop. David Bowie. Aretha Franklin. John Lennon and Yoko Ono. On a day between the sixties and the seventies, all of these people came across the road of photographer Alec Byrne, who did not fail to immortalize this meeting. And who didn’t – until today – shared it with the world. It is now done, with the exhibition London Rocks: The Unseen Archive, installed until January 28 at the Proud Central gallery of London.
