Planet Jarre: 50 Years of Music is a compilation album by French electronic musician and composer Jean-Michel Jarre, released on 14 September 2018 to commemorate Jarre's 50 years in the music business.
A total of forty-one tracks were chosen by Jarre himself for inclusion, among them two new songs ("Herbalizer" and "Coachella Opening"). Jarre remastered, and in some cases "retouched", the tracks himself. During the process, he decided that he had pursued four quite different styles of composition and therefore divided the project into four "universes" - "Soundscapes", "Themes", "Sequences" and "Explorations and Early Works”.

Équinoxe (English: Equinox) 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.

Oxygène (English: Oxygen) is the third studio album by French electronic musician and composer Jean-Michel Jarre and his first album not intended for use as a soundtrack. Oxygène consists of six tracks, numbered simply "Oxygène Part I" to "Part VI". It was first released in France in December 1976, on the Disques Dreyfus record label licensed to Polydor, with an international release following in the middle of 1977. The album reached number one on the French charts, number two on the UK charts and number 78 in the US charts.
