Following the magnificent albums "Heaven and Hell" (1975) and "Albedo 0.39" (1976), not forgetting lesser-known works like "Earth" (1973) and "L'Apocalypse Des Animaux" (1973), Vangelis created one of his masterpieces with his fifth album, "Spiral". With this album, Vangelis began one of his most fruitful periods, both in his use of electronic instruments synthesizers, sequencers, and all kinds of electronic and acoustic keyboards and in the melodic composition of his music. On this new record, he gradually moved away from the progressive and experimental sounds of his earlier work and its complex and intricate compositions, becoming more romantic and grandiose, gaining in simplicity and thereby attracting a wider audience with his accessible electronic music. All of this is demonstrated in tracks like the commercially successful "Dervish D", the addictive epic "To The Unknown Man", and the meticulously crafted "Ballad", "Spiral", and "3+3". Over the next four years, the Greek musician would release a mix of major works and others with less media impact, including the experimental "Beaubourg" (1978), the exotic and brilliant "China" (1979), and the stunning "Chariots of Fire" (1981), among half a dozen other albums.
