I am not downing anything you stated, actually just embellishing typing about it. I am also not upping my abilities when I played. He has some skills and dexterity that, with practice allows that type of playing. I had comparable skills but never in that environment though I did play some in front of people with an orchestra, I played classical but much more enjoyed country along with rhythm medleys as I liked to sing as well (Normally harmonizing if I could find a singer that would lead. (Hard to come across unless you do it for a living.) At different times, self-enjoyment and worship was the key to me.
I will mention a few guitarists I was in awe of watching them play and would not pick up a guitar if they were anywhere near and then I will tell you why. Steve Vai, Roy Clark, Macel Ely, Leonard "Monk" Langford, Jerry Reed, Glenn Campbell, Vince Gill, Chet Atkins. There are a bunch more but these are some I saw and was around in person. (Vince, Glenn, and Jerry in concert only.) (You probably do not know a couple of the people I mentioned as they are not famous nationally.)
These people played nearly as many notes with either hand at times and could play about any type of music at any time. Granted I only listened to the person you shared for the one song. (I did enjoy watching him play.)
Forgive my rant, I am actually talking myself into playing again to see if I can. (Kind of for my Grand children and myself.) When my brother (BIL) died a month or so ago and I went to Michigan, I found he kept one of my guitars for me until I came back to pick it up but I never did. I actually forgot about it. It is an Alvarez guitar and a nice one. My nephew is going to pick it up for me in the next month or two and we shall see. I have an old guitar I keep in my study just to look at as I haven't even strummed it but my grand babies twang it and they have a good time doing it.
We shall see... (Thanks for allowing me to remember...)
