Tristan Jehan is obviously a stylish gentleman with a grasp of what makes culture. He wrote something to work out the beat of a piece of music, time-stretch the first half of each beat and time-shrink the second half. Ladeez gemmun, I give you: The Swinger. “Sweet Child O’ Mine” is probably my favourite here. My toddler daughter thinks all this stuff is fantastic. And my faith in anything on a recording having anything to do with anything a human played just dropped even further.
Update: Someone’s put up a site that does it for you. Some of these are great.
