Recordings of Romantic Era piano concertos

With improvements in recorded sound, the decade of the 1930s had many fine recordings of piano concertos of the Romantic era. Pianists such as Arthur Rubinstein, Wilhelm Backhaus, Vladimir Horowitz and Artur Schnabel had their first opportunities to record concertos by such composers as Liszt, Chopin, Brahms and Tchaikovski. On Saturday at 11, we'll sample those recordings.
