David Gilmour------ RICK WRIGHT >>> R.I.P.Richard William Wright (born 28th July, 1943 London, UK - 15th September, 2008) was the keyboardist for the rock band Pink Floyd. He, along with Roger Waters, Nick Mason and Syd Barrett formed the original lineup of Pink Floyd and was an extremely important part of the early Pink Floyd sound. He made several key contributions but perhaps his best known work with Pink Floyd is The Great Gig In The Sky.
Roger Waters - I'm willing to post him in my guitar players group because he does play some guitar and wrote most of the amazing lyrics for the Pink Floyd albums I love. Also, he has been mending walls with David Gilmour after the fiery official leaving of the band in 1985. His retooling of The Wall tour in 2010 was the best concert I've ever attended.
