Pianist Lucy Parham picks through the greatest recordings of Rachmaninov's 2nd Piano Sonata.

Sergei Rachmaninov's Piano Sonata No. 2, Op. 36, in B-flat minor was composed in 1913 and revised it in 1931. Three years after his third piano concerto was finished, he moved with his family to Rome and started working on his second piano sonata. It is a mighty but technically challenging piece. Rachmaninov himself was not satisfied with the work and revised it in 1931. In 1940, the pianist Vladimir Horowitz created his own edition which combined elements of both previous versions.
