Jon Lord - Deep Purple
Dave Greenfield - The Stranglers
Mike Lindup - Level 42
Don Airey - who hasn't he played with? Amongst others Gary Moore, Rainbow, Deep Purple, Michael Schenker, Ozzy Osbourne, Whitesnake
His videos are excellent. I'm much more of guitar fan but would nominate two players from two of my favourite bands.
Brighton's own Dave Greenfield from The Stranglers and Mike Lindup from Level 42.
Much more of a guitar fan but if I had to choose a couple it would be Dave Greenfield of The Stranglers and Mike Lindup of Level 42. For Lindup forget the later pop albums but check out their early heavily instrumental jazz funk stuff.
