Pink Floyd live in a Stadium performing dark side of the moon in entirety. Big stadium with surround sound speakers. Cartoon sized round video screen above the stage. And the song was “on the run”. On the screen was a film taken off from a stunt plane, which made the audience feel like they were actually flying. Unbeknownst to the audience, there was a wall cable that stretched from the back of the stadium to just above the screen. The film showed the POV flight going right into a cliff. Just as the plane was about to crash, a huge model plane came from the back of the stadium, flew over the audience right to the top of the screen where it was synchronized with the film. Pyrotechnics were set off right at impact. Scare the living shit out of me. Please note, this was a 1974 long before digital technology found its way into modern music.
