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 recognizable album covers of all time, including "The Dark Side of the Moon" and "Band on the Run." 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 center of the maddest, funniest and most creative era in the history of popular music. The film features brand new interviews with Roger Waters, David Gilmour & Nick Mason of Pink Floyd, Jimmy Page & Robert Plant of Led Zeppelin, Paul McCartney, Peter Gabriel, Graham Gouldman of 10cc, Noel Gallagher, and many more!
