I grabbed a used copy of this on Amazon. Sound is excellent. It is old style mastering, big, full EQ, some tasteful compression but not obvious, typical 60s classical sound intended to entertain the listener. Not the modern audiophile flat EQ hyper detail sound. Very lovely and satisfyingly rich and ballsy.
And the playing... wow! She is very expressive and confident. Technique is out of this world, but never intrudes on her artistry or the compositions.
Very different than my Arthur Rubenstein and Garrick Ohlsson Chopin recordings. Thanks for bringing this one to my attention!
