I just recently got into Steve Howe. He's considered one of, if not the best guitarist of all time and I came across a quote he had that said something like he wished guitarists would focus on being musicians. Same thing as coders to engineers. I've come across more technically able programmers than I am. But they aren't better engineers. And a lot of that is because I'm an entrepreneur and have a marketing secondary…
Just a minor note. Howe is good, one of the best yes, but Paco De Lucia reigns far above them all.
I looked up Howe and he said this about Paco:
"There was mention of Paco de Lucía, who is the greatest, well, if not the greatest ever flamenco guitarist. Many people love him dearly as I do, and if somebody says, 'Can you play like Paco?' I say, 'No, no.' [laughs] So I just jumped on board, and it was wonderful. Very nice people." [1]
Howe made up a flamenco piece on the spot for a Queen song so he was talking about Paco then.
The nod is there by the man himself for the greatest flamenco guitarist.
But if you discuss something that is basically subjective, you still need criteria because if one person is saying oh Paco is the most technically skilled that's one thing. Another would be more akin to how the Decathalon decides the greatest athlete.
I don't know if Howe is the best ever, but if there was a Decathalon equivalent for guitarists, I'd bet Howe would top Paco no problem. And in that event, he'd top Jimi Hendrix and Page too. But that's just my benchmark, having range and full command of the discipline.
