All without prearranging from any performer, just cut ups and remixing things he found over YouTube.
Why I wanted to write this post about is not this video but one that he made later and it is one of three. In these videos he made videos travelling around in different places and later cut up the videos he made of people playing and constructing new music out of it.
It is pretty impressive and what a nice hobby project for a vacation.
My point being that with better video cameras directly on our devices it is now totally possible to do these projects ourselves maybe not whole songs but maybe for half a composition to be completed with added music?
First the video that he got attention for that has been posted before and then when he uses videos from a trip in Tokyo.
