Pianophilia

I would like just to ask, if anybody remember on a private recording of Horowitz.
He is playing for his friends some jewish music or improvisation.
I heard this recording years ago and now I couldn't find it anymore, but I did find his interviews, which are amazing.

Horowitz - Chasins interview 1965


Horowitz interview 1975


Horowitz Seminar Ann Arbor 1977

I found the recording, which I like very much.

I found an improvisation on Rimsky Korsakov Coq d'Or as well.
