Query: Rubenstein

In 1967 I heard this on the radio and was late for work to find out what it was. I bought it the next day. In 2009 I lost it and found it only on Amazon. I have probably listened to it 100 times or more. Especially Polish Aires. Grew up on classical music. This is my favorite. Was a concert pianist.
