There are people who play faster (Satriani, DiMeola, Randy Rhodes), and people who play smoother (Dickie Betts, Clapton, David Gilmour), and people who play more interesting or unexpected lines (Hendrix, Jimmy Page), but Duane, if you listen real close, tapped into something really primordial. Listen to the session work on Aretha's version of "The Weight," or the second slide solo in "Mountain Jam." Duane rocked. RIP.
