No, to the best of my knowledge I'm still here. Chick Corea is the one who passed away. He was a superb pianist who managed to do great things in several different Jazz styles and had even recorded classical pieces. He wasn't content fitting into a particular mold.
Wayne was referring to an email thread, not part of this forum, that was discussing Mr. Corea. I'd been lucky enough to photograph Mr. Corea at the Newport Jazz Festival in 2006 and was relaying the story.
There are too many great musicians who have passed to be able to list them all, frankly. Even if you limited it to a particular instrument like bass or trumpet there would still be too many. We're just lucky to live in an age where these folks leave behind their recorded legacy.
