Magma is a French progressive rock band founded in Paris in 1969 by self-taught drummer Christian Vander, who claimed as his inspiration a "vision of humanity's spiritual and ecological future" that profoundly disturbed him. The style of progressive rock that Vander developed with Magma is termed "Zeuhl", and has been applied to other bands in France operating in the same period, and to some recent Japanese bands.

Vander created a fictional language, Kobaïan, in which most lyrics are sung. In a 1977 interview with Vander and long-time Magma vocalist Klaus Blasquiz, Blasquiz said that Kobaïan is a "phonetic language made by elements of the Slavonic and Germanic languages to be able to express some things musically. The language has of course a content, but not word by word." Vander himself has said, "When I wrote, the sounds [of Kobaïan] came naturally with it—I didn't intellectualise the process by saying 'Ok, now I'm going to write some words in a particular language', it was really sounds that were coming at the same time as the music." In the course of their first album, the band tells the story of a group of people fleeing a doomed Earth to settle on the planet Kobaïa. Subsequently, conflict arises when the Kobaïans - descendants of the original colonists - encounter other Earth refugees. Later albums tell different stories set in more ancient times; however, the Kobaïan language remains an integral part of the music.

In 1986, the French label Seventh Records was founded to (re-)publish Magma's and Vander's work. Over the years, Seventh has also released albums by related artists such as Stella Vander, Patrick Gauthier, and Collectif Mu.
