The film preceded the release of the psychedelic warriors’ landmark 1973 Dark Side of the Moon album, with the band setting up in the ruins of the ancient Roman Amphitheatre in Pompeii, Italy in October 1971 for a gig without an audience. It was the first live concert set in one of the oldest surviving amphitheaters in the world, built in 70 B.C.

On April 24, a digitally remastered version of the movie will be beamed into standard and IMAX theaters around the world.
