personally-I-think-he's-in-at-least-the-top-15-for-me vote Neil Young 20th on their list of 100 Greatest Guitarists of ALL Time:

But no one combines those elements like Shakey, and that slow, craggy soloing style — the aural manifestation of the man’s skewed thought process — is straight-up sui generis
Most Heroic Moment: The graceful, arcing lines that open the second solo on 1979’s “Powderfinger.”
