The keyboard player for Pink Floyd. Only 65.
He didn't get as much attention or credit as either Roger Waters or David Gilmour, but he probably should have: the keyboards were really at the very heart of Pink Floyd's music.
In fact, between Piper at the Gates of Dawn and Dark Side of the Moon, it sometimes seemed as though the other three members would just let him improvise for twenty minutes and call it an album side.
Major experimental outngs like "On the Run" from Dark Side of the Moon were entirely Wright just letting his imagination run wild on the keyboard.
He had an astounding musical imagination, and he used it to help make some of the best, most important and most influential music in the history of Rock.
