Doing some reading of back issues...
From the NY Time of 28 December 2005
"Constance Keene, a pianist and teacher whose recordings of the
Romantic keyboard repertory were highly regarded, died on Dec.
24 at Lenox Hill Hospital. She was 84, and lived in Manhattan."
I only remember her recording of the Rachmaninoff Preludes, a 2 disc set
which I still have.
