Is he really that good? It takes a lot more than just technique to make a great guitarist.
Whatcha got? Post a YouTube link, maybe of something live...
I don’t have a particular link handy, but if you search YouTube for “Phil Keaggy Salvation Army Band Wheaton”, you’ll find various recordings of his song, Salvation Army Band, performed live at Wheaton College. It’s phenomenal. You could also search for his recorded track, “The Further Adventures Of...”, which is just an entirely improvisational session with only himself and a drummer. It is really incredible.
Also, if you want to hear the absolute quintessential Keaggy on acoustic guitar, look up his album “The Master and the Musician.” It’s a classic, and just transports you to another place.
