Very good. What's not to like? New strings never sounded so good. Since you used the word "performance," I'll add that I'm pretty sure the audio and video were recorded separately (Derek beat me to it!). There might even be an overdub starting around 0:05, but it looks like he's really playing everything, with no trickery. I've watched it twice, and his left thumb is visible for a single brief moment (just the tip of his thumb). Very good playing and arrangement. Congrats to Luca and I hope he doesn't get into trouble when/if management see what he did in the company warehouse.
