DVD Region 4. Celebrated photographer, creative director and filmmaker Anton Corbijn's first feature documentary Squaring the Circle (the story of Hipgnosis) tells the story of Storm Thorgerson and Aubrey "Po" Powell, the creative geniuses behind the iconic album art design studio, Hipgnosis, responsible for some of the most recognisable album covers of all time. They formed Hipgnosis in Cambridge during the ferment of the sixties and became rock royalty during the boom time of the seventies. They conjured into existence sights that no one had previously thought possible, produced visuals which popularized music that had previously been considered fringe, and were at the white-hot centre of the maddest, funniest and most creative era in the history of popular music..
