Dennis Morris is one of Britain's most successful photographers, whose images of Bob Marley and the Sex Pistols helped define the art of rock photography. He started out taking pictures on the streets of Hackney and his early photography offers a striking documentary portrait of London's black community in the 1960s and 70s. In the year punk turns 40, and with an exhibition of his work with Public Image Limited opening at the ICA, this film follows Dennis at work, photographing an up-and-coming new punk band. We also follow Dennis back to the places that inspired his early work, and he recounts life on the road with Bob Marley and the Sex Pistols.
