Just come accorss the phenomenon of 'tapping' guitars, and the associated new ways of playing it. Pioneered by Mike Dawes, if I'm not mistaken, but there are several guys doing it now and taking things to insane levels...
Something similar is Warren Huart's channel Produce Like A Pro. He also does video analyzing how songs were made, influential artists, and the different aspects of the recording industry. He just did a two part tour of the legendary FAME recording studios in Muscle Shoals, Alabama home of the "Muscle Shoals Sound". I was born across the river in Florence, AL but have never been inside FAME so that was great to watch.
Another great channel if you love racing cars both modern and vintage is 19Bozzy92. I'm always posting his videos over in the Brilliant Racing Videos thread. He gets up close access to track days at some of the best European tracks like Monza, Imola, etc.
People like this are why YouTube is great. Forget about all the stupid people that do stupid things, this is quality content right here. And if I had a 4WD vehicle I would definitely help out and volunteer.
