A true late 20th century musical pioneer and hugely talented.  He trail-blazed in a most unique and formative time in history of pop/rock music.  Music critic's didn't get ELP and demonized them but true music lovers out there knew they were hearing something unique, new  and special and it all revolved around Keith Emerson.   A huge loss.

R.I.P.
Amazing mastery of keyboards and composition.  Sure he "borrowed" the works of other composers, particularly classical, but in his re-orchestration, brought new life into those classics.
How ironic.  I have been listening to them lately and just received a UK pressing of Brain Salad Surgery.  I will definitely be listening with a different view. I always liked those guys.
