Vangelis - Rêve [Stretched] 

Rêve is the 2d track from the album "Opera Sauvage" (1979)
Opéra Sauvage is a soundtrack album by the Greek electronic composer Vangelis, released in 1979. It is the score for the nature documentary of the same title by French filmmaker Frédéric Rossif. It is considered one of Vangelis' best albums, and is his second most successful album in the USA, reaching #42 in the album charts.
Vangelis produced this album during his electro-acoustic period, which was one of the most productive in his musical career. Opéra Sauvage is more akin to his classic sound than his earlier nature scores for the same director, Frédéric Rossif, such as L'Apocalypse des animaux and La Fête sauvage. A later collaboration with Rossif in the style of Opéra sauvage was Sauvage et Beau.
