Алекса́ндр Никола́евич Скря́бин
Scriabin was a Russian composer and pianist. Scriabin, who was influenced by Frédéric Chopin, composed early works that are characterised by tonal language. Later in his career, independently of Arnold Schoenberg, Scriabin developed a substantially atonal and much more dissonant musical system, which accorded with his personal brand of mysticism.
Scriabin was influenced by synesthesia, and associated colors with the various harmonic tones of his atonal scale, while his color-coded circle of fifths was also influenced by theosophy. He is considered by some to be the main Russian Symbolist composer.
Here is a link to Scriabin's The Poem of Ecstasy
"Here you will find probably the most ecstatic music on earth : Alexander Scriabin's "Poem of Ecstasy" op. 54 also known as his 4th symphony. It is like a long symphonic poem of about 20 minutes composed on a long (about 8 pages) epic-like poem wich Scriabin wrote himself. It tells the long course of the spirit through the space, liberated from the human body"
