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.
May 8th,1984, Roger Waters released his first solo album The Pros And Cons Of Hitch Hiking. The concept album, as originally envisioned by Waters in 1977, rotated around a man's thoughts during a midlife crisis, and featured guest musicians Eric Clapton on guitar, David Sanborn on saxophone and Michael Kamen on piano.
