Equinoxe is the fourth studio album by French electronic musician and composer Jean Michel Jarre , released in December 1978 on the Disques Dreyfus record label, with license to Polydor. Jarre had developed his sound, employing more dynamic and rhythmic elements, particularly a greater use of sequencing on basslines. Much of this was achieved using custom equipment developed by his collaborator Michel Geiss. The album is presented as two suites of music, each consisting of 4 parts and taking up one side of the vinyl release of the album. The separate tracks on the record smoothly segue into each other to this effect. The album reached number 11 on the UK Album Chart and number 126 on the US Billboard 200 chart. A cover version of "Équinoxe Part 5" by the Shadows reached No. 50 on the UK singles chart in August 1980. During the 1980s, "Équinoxe Part 4" was used in the opening credits of the TVNZ documentary series Our World.
