These days, you just don’t get virtuoso synth players (which some might argue is a good thing) but in the ‘70s, Rick Wakeman’s solos were as legendary as the Arthurian myths on which he based one of his albums (he also played keyboards with prog outfit Yes). The story goes that Wakey bought his first Minimoog from Jack Wild, the child star who played The Artful Dodger in the film version of Oliver!, because the young lad thought it was broken when he discovered that it only played one note at a time. Bless.
“Keith Emerson. Rick Wakeman. Bob Moog. Walter Carlos. All for obvious reasons. Others we shouldn't ignore: Peter Bardens, Pete Townshend (Who's Next was a masterpiece).” (Thanks, musophilr)
