Throughout the 1970s, Vangelis composed 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 1975 he set up his new 16-track studio, Nemo Studios in London, which he named his "laboratory", releasing many solo albums on which experimented with music and concepts, including Heaven and Hell and China among others. In the early 1980s, Vangelis formed a musical partnership with Jon Anderson, the lead singer of progressive rock band Yes, and the duo released several albums together as Jon & Vangelis. He also collaborated with Irene Papas on two albums of Greek traditional and religious songs.
