1930s Electronic Music With Animation 4K Restoration "Paper Sound" Nikolai Voinov
This was made back in 1930s Soviet Russia using an optical synthesizer called that variophone which takes a picture of a drawn waveform on replicates it. Sounds are drawn and paper and then dragged across the aperture to play a song. It amazes me that electronic music goes back this far and I think sounds so futuristic so I took the time to restore this little known piece
There are more of these with animations if anyone is interested
