Ren. Is this guy a genius or just passing fad?

I'm not really a muso, but I do watch some random music related channels on Youtube. The algorithm has suddenly been pushing all sorts of videos from many channels reacting to this video by Ren, so I figured it must be worth a listen.

And so I did. Wow! Probably the most unusual track I've listened to for a long time. Insane talent. Literally. I don't see this guy mentioned in any threads on PH, so thought I'd start a thread and see what you guys think...
