Evangelos Odysseas Papathanassiou (Greek: Ευάγγελος Οδυσσέας Παπαθανασίου [evˈaɲɟelos oðiˈseas papaθanaˈsiu]; born 29 March 1943), known professionally as Vangelis (Greek: Βαγγέλης [vaɲˈɟelis]; English pronunciation: /væŋˈɡɛlᵻs/), is a Greek composer of electronic, progressive, ambient, jazz, pop rock, and orchestral music. He is best known for his Academy Award–winning score for the film Chariots of Fire, composing scores for the films Antarctica, Blade Runner, Missing, 1492: Conquest of Paradise, and Alexander, and the use of his music in the PBS documentary Cosmos: A Personal Voyage by Carl Sagan.
After having taking piano lessons from renowned Greek composer Aristotelis Koundouroff, Vangelis began his professional musical career working with several popular bands of the 1960s such as The Forminx and Aphrodite's Child, with the latter's album 666 going on to be recognized as a psychedelic classic. Throughout the 1970s, Vangelis composed music scores for several animal documentaries, including L'Apocalypse Des Animaux, La Fête sauvage and Opéra sauvage; the success of these scores brought him into the film scoring mainstream. In the early 1980s, Vangelis formed a musical partnership with Jon Anderson, the lead singer of progressive rock band Yes, and the duo went on to release several albums together as Jon & Vangelis.
