Glad to see another mention of Mitsuku Uchida, her Mozart Piano Concertos are my favorites, and I have many other recordings of them. Also her Schubert. I'm lucky to have lived in NYC for a very long time, and so have seen most of the greats from the 1970s on.
I met my wife at a very young age, as a teenager in fact, and we started going to classical music concerts back then. One day we went to Carnegie Hall to see Ashkenazy. She only told this to me recently, but she said that was the concert when she finally 'got' classical music. I guess that counts for something.
