"Magma underwent several personnel changes: guitarist Claude Engel departed without being replaced, and Alain Charlery and Richard Raux made way for Louis Toesca (trumpet) and Jeff Seffer (sax, bass clarinet). This was the second installment in Magma's Kobaïan saga. With lyrics again performed in the band's invented language, the album chronicles the Kobaïan people's return to Earth to save the planet."
—Wilson Neate, Review of 1001° Centigrades on Allmusic
This album, along with their first - Kobaia (1970) - is more jazz fusion based than their future albums. The Zeuhl sound is developing: The adventurous structures are in place, but the arrangements are dominated by horns. The operatic female vocals and primal driving rhythm of the next album Mëkanïk Dëstruktïẁ Kömmandöh (1973) are not yet in place.
After this album and before the release of their third MDK (1973), a number of band members left the band due to disagreements in the future sound of the band. Two (saxophonist Yochk'o "Jeff" Seffer and keyboardist François Cahen) left to form Zao, a band which follows in the footsteps of Magma's first two releases.
