Those ranking lists always make me laugh.
Mark is always underrated. (same for JJ Cale, David Gilmour & Tony Joe White )
You're right Jackal, it's all about technical abilities.
They consider MK doesn't have a great technique because he doesn't play with a pick.
I don't agree. Satriani can play faster than MK, and then ?
Let's do it simple. Mark has played with many great guitarists, for example RS#2 EC, Chet Atkins or recently Bob Dylan on Don't think twice it's alright.
I don't think he's ever been ridiculous while playing on the same stage.
Not sure if I agree with what you say here. "They" (RS, I believe you mean?) don't underrate Mark (or Gilmour) because of technical ability, but rather they try to measure how influential and innovative the guitarists are or have been. I mean, Keith Richards is number 4 ...
And neither is Mark underrated because he plays with his fingers. Other fingerstyle players are ranked higher, for instance Derek Trucks at #16.
I think the list is OK IF you consider the fact that it is NOT a ranking based on technical ability.
For me the bottom line is this: Does the guitar player (or musician) move you? They can be highly revered or unknown, technically good or bad, but if their playing strikes a chord (no pun intended) in your soul, then that's the player who's best for you. And this is why I have loved Mark's playing all these years. His tone, taste, ability to squeeze out emotions of that fretboard in a way that other more technically skilled guitarist only can dream of. And he can do that with three notes ... I might not be crazy about everything he does musically these days, but when he's on form, he's among my absolute favorites.
