Founding member of Deep Purple, keyboardist Jon Lord, has died of pancreatic cancer. He was 71. link.
Lord's "monster" hammond sound was synonomous with 70's rock. Saw him with Purple 3 times back in the 70's/80's. Always a great show.
What I, personally, consider his "crowning achievement", the Concerto for Group and Orchestra is available on Netflix.
Rest in Peace, Jon...say "hi" to Ronnie for us.
