To mark the fortieth anniversary of Joy Division's seminal album Unknown Pleasures, celebrated rock photographer, Paul Slattery, travels back in time to Saturday 28 July 1979.

His new book features the iconic images of the photo session of the band which he took on the streets around Strawberry Studios in Stockport (where the band recorded the album) and later that day at the legendary "Stuff The Superstars" gig at The Mayflower Club in Gorton.

This is the first time all the images have been published in one volume. Paul shares his memories of the day, and the photographic locations, along with some never-before-published images.
