Sergei Rachmaninoff
Sergei Vasilievich Rachmaninoff (Russian: Сергей Васильевич Рахманинов, Sergej Vasil’evič Rahmaninov, 1 April 1873 [O.S. 20 March] – 28 March 1943) was a Russian-American composer, pianist, and conductor. He was one of the finest pianists of his day and, as a composer, very nearly the last great representative of Russian late Romanticism in classical music. Early influences of Tchaikovsky, Rimsky-Korsakov and other Russian composers gave way to a thoroughly personal idiom which included a pronounced lyricism, expressive breadth, structural ingenuity and a tonal palette of rich, distinctive orchestral colors.
The piano features prominently in Rachmaninoff's compositional output, either as a solo instrument or as part of an ensemble. He made it a point to use his own skills as a performer to explore fully the expressive possibilities of the instrument. Even in his earliest works, he revealed a sure grasp of idiomatic piano writing and a striking gift for melody.
Most famous for his Piano Concerto #2 in C minor and Piano Concerto #3 in D minor, as well as his piano-solo Prelude in C-Sharp Minor, Op. 3 #2. The third concerto was featured in the movie Shine, for what it's worth.
