Koyaanisqatsi

If you don't have time to watch the whole movie, well, here's it in 4 minutes...
My version of the Koyaanisqatsi theme is played on 2 ukuleles (Excelsius concert) and a Minimoog synth (Bass). I also 'sing' here.

I saw the film years ago. It can be rather hypnotic and fascinating.

On the other hand, if you are not in the right mood I could see how it might drive one insane.
