Query: Possibly the best Scarlatti recording ever

Ms. Tomsic, a former student of Arthur Rubinstein, is little known. Yet she is a pianist of the very first rank, and her Scarlatti recording may be the finest ever, amid tough competition (Horowitz, Michelangeli, M Meyer, Zacharias a.o.)The beauty of her music-making is superlative.
