This is an absolute gem as documented by Life Magazine. God Bless YouTube for such an archive retrieval.. The beautiful A Minor Piano Concerto of Robert Schumann played by Artur Rubinsein with the RCA Victor Symphony Orchestra and William Steinberg.
This 1947 recording has to be the definitive version of this piano concerto as I have not heard a better version going backwards. The next best is Wilhelm Backhaus with Leipzig and Clemens Krauss.
