Having just posted on another thread regarding guitar players, it made me think of opening up a debate on who people might consider to be the greatest ever? For me, my number one would be the great blues legend and mythical figure, Robert Johnson (super-natural technique; essence of blues music; from which blues, rythym and blues, rock 'n' roll, Stones, Dylan, rock music, etc, has all morphed from.) I can't think of a single more influential guitarist in the history of contemporary music (although he was also, of course, a mesmerizing singer and a hauntingly beautiful songwriter.) So then, who do you all rate as your own number one on guitar?
