http://en.wikipedia.org/wiki/Alexander_Scriabin
Alexander Nikolayevich Scriabin[1] (6 January 1872 [O.S. 25 December 1871] – 27 April [O.S. 14 April] 1915) was a Russian composer and pianist who initially developed a lyrical and idiosyncratic tonal language inspired by the music of Frédéric Chopin. Quite independent of the innovations of Arnold Schoenberg, Scriabin developed an increasingly atonal musical system, accorded to mysticism, that presaged twelve-tone composition and other serial music. The first major example of this is the 5th piano sonata of 1907, although the process of innovation was somewhat gradual. He may be considered to be the main Russian Symbolist composer.
Scriabin influenced composers like Roy Agnew, Sergei Prokofiev, Nikolai Roslavets and Igor Stravinsky, although Scriabin was reported to have disliked the music of both Prokofiev and Stravinsky.[2] The work of Roslavets, unlike that of Prokofiev and Stravinsky, is often seen as a direct extension of Scriabin's. Unlike Scriabin's, however, Roslavets' music was not explained with mysticism and eventually was given theoretical explication by the composer. Roslavets was not alone in his innovative extension of Scriabin's musical language, however, as quite a few Soviet composers and pianists such as Sergei Protopopov, Nikolai Myaskovsky, and Alexander Mosolov followed this legacy until Stalinist politics quelled it in favor of Socialist Realism.[3] Scriabin's importance in the Soviet musical scene, and internationally, drastically declined. "No one was more famous during their lifetime, and few were more quickly ignored after death."[4]
Scriabin was one of the most innovative and most controversial of early modern composers. The Great Soviet Encyclopedia said of Scriabin that, "No composer has had more scorn heaped or greater love bestowed..." Leo Tolstoy once described Scriabin's music as "a sincere expression of genius."[5]
