split of The Forminx, Vangelis spent the next two years mostly studio-bound, writing and producing for other Greek artists. He scored music for three Greek films; My Brother, the Traffic Policeman (1963) directed by Filippos Fylaktos, 5,000 Lies (1966) by Giorgos Konstantinou, and To Prosopo tis Medousas (1967) by Nikos Koundouros. During this time, Vangelis worked on the scores to Frenzy (1966) for director Jan Christian, Apollo Goes on Holiday (1968) for George Skalenakis and Antique Rally (1966). In 1968, the 25-year-old Vangelis wished to further his career and, amidst the political turmoil surrounding the 1967 coup, left Greece for London. He was denied entry into the UK and settled in Paris for the next six years. Later in 1968 he formed the progressive rock band Aphrodite's Child with Demis Roussos, Loukas Sideras, and Anargyros "Silver" Koulouris. Their debut single, "Rain and Tears", was a commercial success in Europe which was followed by the albums End of the World (1968) and It's Five O'Clock (1969). Vangelis conceived the idea of their third, 666 (1972), a double concept album based on the Book of Revelation. It is widely recognized as a progressive-psychedelic rock classic. After increasing tensions during the recording of 666, the group split in 1971. Vangelis would produce future albums and singles by their singer Demis Roussos. Vangelis recalled after the split: "I couldn't follow the commercial way anymore, it was very boring. You have to do something like that in the beginning for showbiz, but after you start doing the same thing everyday you can't continue." From 1970 to 1974, Vangelis took part in various solo projects in film, television, and theatre. He composed the score for Sex Power (1970) directed by Henry Chapier, followed by Salut, Jerusalem in 1972 and Amore in 1974. In 1971, he took part in a series of jam sessions with various musicians in London which resulted in two albums released without Vangelis's permission in 1978: Hypothesis and The Dragon. Vangelis succeeded in taking legal action to have them withdrawn. 1972 saw the release of his debut solo album Fais que ton rêve soit plus long que la nuit, French for Make Your Dream Last Longer Than the Night. It was inspired by the 1968 French student riots, after which Vangelis decided to write a "poème symphonique" to express his solidarity with the students, comprising musical with news snippets and protest songs; some
