I found these reels of outtakes at archive-org.
I cut them up and stacked them up to build a videowall and applied some rotation and other stuff in V-Track.
I also kept all the mistakes because they added to the uniqueness of the footage.

Soundtrack was done in Logic8 using Mr.Ray Mk2 for the Rhodes, EZdrummer/Jazz with the beats of David Haynes. RMX for the electronic Percussion. Trilogy for Bass and Omnisphere for the lead synth sound
