Two of Rachmaninoff’s great piano works, from two distinct phases of his compositional career. The Variations are based on the same theme, not “by” Corelli, but used “by” Corelli in his violin variations on the Follia. They were composed in 1931, at the beginning of the composer’s Swiss period. The Études-Tableaux are two sets of piano pieces of great virtuosic challenge and symphonic scope, written in 1916, when the composer was still living in Russia. The one presented here is the second set.
