A lot of talent combined with some unusual tuning delivers an impressive result:

Wow - that's incredible!!!

That is a 9 string, extended range guitar:

Factory Tuning - which is classic tuning with three more bass notes added moving down (or is it up?) the circle of 5ths.

Wow! That's crazy! And an amazing talent too!

Then there's this.

Yes, there is. Physical sculptures, sans extraordinary guitar licks.

Actually, I believe this instrument is designed to be played with drumsticks. In which case, any sound that comes out of that thing (and note that it is plugged into an amp!) would be “extraordinary“.

Yes, I noted the amps in some of the still images.

I wonder if you could find an example of one of these being played? I'd be interested. I understood that they are just 'sculptures' (their term).

One could play them with drum-sticks to make a sound as you suggest, although this wasn't indicated except for the single image of a spiral of drums glued to a wall in an anti-clockwise direction ('transmigration').

However, dropping any of these guitars from a great height would also deliver an "extraordinary" sound I suppose. As for extraordinary guitar licks? Well, I'm not so sure.

Didn't watch the whole thing, don't know if he makes it all the way to the top.

I watched. He awkwardly (and very non-musically) makes it to about 11th out of the 12. (Clearly he's way over his head at 12).

There was some applause at the end, but I'm guessing it was in appreciation that he had finally finished the performance
