Happy to oblige 
This trombone performance (starts at 14:41 and it should be linked to start there). The guy starts a solo at 15:03 and it’s like…what?? That kind of breath power to make such a loud, flawless sound and to still have the energy to hit such a range of notes. My lip hurts just listening to it. AND this is after they had marched their show, and participated in some back-and-forth with the other band. I bet the world’s best classical jazz trombonist couldn’t even do this without a ton of practice. It’s very hard to make a loud trombone sound this good.
Sure Everybody has heard Pachelbel’s Canon ad nauseum but I bet you never heard it quite like this. As it goes along it just keeps getting better and better and better and better…

Not sure why I don’t get the nice embedded YouTube link, but if you click on that it’s worth it I promise.
The guy who did the original wasn’t too shabby either.
Yep, you beat me. Still blows me away.
Johnny Winter - “Mean Town Blues” live at Woodstock, 1969
An awesome version played on a 12 string guitar with only 6 strings on it for extra bending space.
“They say if you remember Woodstock, you weren’t there, and that’s pretty much right,” Winter said. “I don’t remember a whole lot. I was tired and asleep on the bus when we got the call to be onstage. I’m surprised it’s as good as it was because I was half-asleep when we began. We played and left. And of course we weren’t in the movie. It was my manager’s idea to not be in the movie; the festival lost money, so he figured the movie would too. He always said it was the biggest mistake he ever made.” - Johnny Winter Looks Back, Through the Songs That Made Him Famous – Texas Monthly
You’re not kidding. Not being a big jazz fan I had never heard if her but that put a smile on my face.
And I found her lovely cover of the Beatles Blackbird Hiromi - Blackbird (Official Audio)
Dr. John and Etta James
One of my favorite performers - Geoff Achison:
I know the OP asks for a short explanation, but no explanation is needed here.
So much guitar and yet I can’t not add this one.
One of my favorites from him is this clip of him warming up. It’s amazing that he walks onto the stage yawning and then plays this.
There’s a longer version of it (here), towards the end, around 14 mins in, you can tell something went wrong. The drummer is looking over his shoulder, people start moving around on stage and eventually the music stops and we see that the piano(?) player’s bench broke and he fell. I don’t recall if I read it in the comments or if I read it here, but I never noticed it until someone mentioned either that that was them or that they were with the crew or something along those lines.
And, of course, we can’t forget about Stevie Ray and Jimmy playing the same guitar at the same time.
These guys are simply amazing. These two videos, IMO, are particularly good.
Sorry for not saying what we should be looking for. The high fret work. The low fret work too. Just all 'round impressive.
I found Rockloe via this Hotel California solo cover. All her covers are amazing, but I particularly like this song (just in general and her cover):
Cool. I like these two guys on the street in Jerusalem (Breslev Brothers). Guy on the Strat has really got Gilmour’s phrasing down. I like how he handles the keyboard solo, with his pinky on the volume knob.
You might think there are three people playing…but Luca plays a three-necked guitar. Quite the one man band! I’m not clear on the tech, but I think that bottom neck has a widget that he uses to record the part on the first pass, play back.
Encore? Here’s “Thriller,” using two standard separate guitars.
When talking about this subject, this has to be included in any suchlike.
This is always a fun one to watch:
(I’m so tempted to jump down the Postmodern Jukebox rabbit hole. They have no shortage of impressive musical performances)
