In 1981, Greek composer Vangelis was a proverbial hot Hollywood commodity, who had just scored an Oscar for his soundtrack to “Chariots of Fire.” A reformed psych-rocker — he used to play keyboards in a Greek psych-prog outfit called Aphrodite’s Child, whose 1972 album “666,” a concept album about the Book of Revelations, is itself something of a cult classic record — Vangelis had previously collaborated with director Ridley Scott on a highly sensuous 1979 commercial for Chanel No.
