The Dark Side of the Rainbow
The Dark Side of the Rainbow – also known as Dark Side of Oz or The Wizard of Floyd – is the pairing of the 1973 Pink Floyd album The Dark Side of the Moon with the 1939 film The Wizard of Oz. This produces numerous moments of apparent synchronicity where the film and the album appear to correspond. Members of Pink Floyd and the Dark Side of the Moon engineer Alan Parsons denied any intent to connect the album to the film.
