I had completely forgotten how good that music album is. I had not listened to it in at least 4 decades. I just rediscovered it and other work from Jean-Michel Jarre in the past couple of days whilst working on my music playlists on Deezer. The album came out in 1976 in France and a year later internationally. It sold (registered sales) over 18 Million copies.
Oxygene remains one of the most sold electronic music album of all times.
Another album of his, among others, is Equinoxe which came out in 1978
