The Beatles 

    "Randomness as art appealed to all of the Beatles very much. The idea that a silent movie selected at random could link up with a piece of music equally randomly picked out was a great wheeze; they loved playing around like that. It's the 'Hey, wow, man, look at that' school of art, the art of the (psychedelically or otherwise) 'liberated' consciousness that was all the rage at the time." -Sir George Martin With A Little Help From My Friends (pg. 138)
