I'll open with Stevie Ray Vaughan.
May I add these three for your approval Eric Clapton, Carlos Santana, and Jerry Garcia. Can’t leave out Keith Richards.
Longevity (from Glass Harp in '71 or so until today and still going strong) and absolute, unspeakable, versatility, way ahead of the curve (e.g. I saw him in concert doing Amazing Grace on the E-bow back in 1980). Who else had *heard* of the E-bow back then?
Virtuoso on both electric and acoustic.
His albums don't do him justice, you have to see him live.
Cheers!
