In short, someone took a piece of software, specifically a StyleGAN, and had it generate faces in real time while modifying its parameters according to a music file. It’s oddly hypnotic.
Hypnotic, or nightmare fuel?
It starts out innocently enough, but once that base starts, it’s like watching “The Ring” to music.
IMHO I found that to be a bit un-easing and a little disturbing. Perhaps an example of just because you can do something doesn’t mean that you should. 
Try watching it at 1/4 speed.
