Pompeii, 1971.

A dead city at the foot of a volcano. A two-thousand-year-old amphitheater, empty of everyone but the band. No crowd, no lights but the sun, just stone that has stood since Rome and music pouring into it. Vesuvius on the horizon, the same mountain that buried this place alive. Ancient world and psychedelic sound, collided. The most beautiful concert no audience ever saw. Now you're the audience.
