'Squaring the Circle (The Story of Hipgnosis)' trailer takes us behind rock's most iconic album covers

You might not know the name Hipgnosis, but you've definitely seen this creative duo's work. You might even have copies of it in your house right now.

Storm Thorgerson and Aubrey "Po" Powell, aka Hipgnosis (the G is silent, like lasagna), founded the design firm in the late '60s. And along with later members (including Peter Christopherson of Throbbing Gristle), they created album covers for some of the biggest names of the 1970s. The most famous is Pink Floyd's Dark Side Of The Moon — triangle, rainbow, you know the one — but there are dozens and dozens more.

Anton Corbijn — the Dutch photographer and filmmaker, himself no stranger to creating visuals for iconic music — has clearly called in some serious favors to tell the story of Hipgnosis in his new documentary Squaring The Circle (The Story of Hipgnosis). The lineup of talking heads alone would be a Glastonbury for the ages: Paul McCartney, Roger Waters, Jimmy Page, Robert Plant, Peter Gabriel, Noel Gallagher, and more.

Squaring The Circle (The Story of Hipgnosis) opens in New York in June 7, in Los Angeles June 16, with a nationwide expansion on June 20.
