“I don’t shoot for the gallery wall,” Kevin Cummins tells me. For an era-defining artist who’s about to have his work displayed in a retrospective travelling from Paris to London, that may seem an incongruous turn of phrase. Half an hour with the man behind the camera, however, and it makes more sense. The Mancunian photographer may have made it his life’s work taking gritty, defining images of bands from his hometown and beyond, and he may be being celebrated in Disclosure, an exhibition featuring some of his most iconic rock images from a career that’s spanned 40 years, but the man himself has never done his job with one eye on the resultant exhibition.
