Sad news.
I first heard George Duke in the context of Frank Zappa and the Mothers. From there, I went on to his work with the Cobham/Duke band and his solo albums. He had such a supple touch on the Fender Rhodes; I can’t think of anyone else who has that level of dynamic control.
I just came across this today - George Duke tests the Rhodes 7 at NAMM 2008. Just look at how much joy there is in his playing…
I’m another who first heard George Duke because of his work with Frank Zappa, then sought out his other work. I’m particularly fond of the stuff he did with John Scofield in the late '80s.
RIP Mr. Duke; you done good.
