Rachmaninov's 2nd Piano Sonata was extensively revised by the composer in 1931, and the revised version is tighter and thinner in texture than the original version of 1913. It represents a supreme challenge to the pianist in either version, and has all the hallmarks of the composer at the height of his powers. The 6 Moments Musicaux Op.16 are early works which exhibit the flamboyance of the youthful virtuoso. Sonya Bach includes three of the Preludes from the Op.23 set.
