Picture this: someone you know has just picked up the guitar for the first time – a friend, loved one, student. They come to you and ask: which guitarist should I listen to and really study? Who can I learn the most from?
Obviously, there's the consideration of the genre the aspiring player is partial to, but some lessons are universal. Equally obvious is that you probably wouldn't want to just pick one, but shhh, that's not the point!
