One reviewer said that Duane Allman was the only person he'd ever heard who could solo over a one-chord vamp for half an hour, and not only not bore you, but leave you absolutely riveted. He asked him how he did it, and Duane said, "That kind of playing comes from listening to Miles Davis's 'Kind of Blue.' I've listened to it so much in the past few years I've hardly listened to anything else."

That tid-bit is from the liner notes for "Kind of Blue," some reissue or other.
