[1] Released in 1972, the album shows a more accessible jazz fusion sound, in an attempt to reach a broader audience, compared to the harsher, less accessible sounds of Magma's self-titled debut album.

Recorded by essentially the same line-up as on 1001° Centigrades (1971), the album basically repeats the stylistic development shown through Magma's first two albums, while abandoning the science fiction concept of the Kobaïan story.

Three tracks from Lasry and one from Cahen on the first half of the album approximate the accessibility of the better-known jazz-rock of the time.

Vander's pieces on the second half of the album, however, begin to explore similar musical ground to that found on 1001° Centigrades.

Two of Vander's pieces can also be found on the 1970 soundtrack to 24 heures seulement and are available on the Archiw I CD in the Studio Zünd 12 disc box collection.
