@willgolf - true about Pat Metheny, but that is true about almost everyone, except maybe Neil Young. Although Pat's newest double album from last year is very reminiscent of his early incredible albums. Not "experimental" at all.
I've heard of Al DiMeola. I'll have to check him out. Never heard of the others - I'll check them out too. It's hard for me to listen to new groups unless they happen to be on Sirius when I drive my wife's car and they allow their songs on the Real Jazz or Watercolors stations. It's hard to roll the dice for $25 for vinyl if I'm not sure I'll like it and play it. The last new one I checked out was John Scofield, who was recommended by my brother in law. It was pleasant/nice enough, but nothing special. I considered him a poor man's Larry Carlton (who also is not a favorite, but since he recorded with Steely Dan for a while back in the day I have a few of his CDs, which rarely get played).
For me other jazz guitar favorites are Earl Klugh, George Benson and Lee Ritenour. As far as rock, Mark Knopfler/Dire Straits, Steve Howe/Yes, Brian May/Queen and of course Clapton are at the top of my list.
Please don't forget the GOAT who most (at least the jazz guys) claim to be their idol, Wes Montgomery (R.I.P.). His collaboration albums with Milt Jackson and Jimmy Smith are 2 of my favorite albums. Also his recording with Miles' band, Full House is incredible.
