"La Cage" is the 1971 debut single by Jean Michel Jarre. Although produced in 1969, Jarre was unable to find a record label that was willing to release the single due to its experimental sounds. After a few rejections, he found Pathé Marconi willing to release it in 1971, but the single turned out to be a commercial failure, with only 117 copies sold. Pathé Marconi destroyed the remaining stock. However, the master tape of "La Cage" was preserved, and as a result the song was featured on the compilation Made in France in 1978. The single can also be found on the Rarities I bootleg compilation in 1994, while the rhythm of "Erosmachine" was reused throughout the track "Chronologie 2" from his 1993 album Chronologie.
Jarre himself had lost his copy during a move and no longer owned it until a fan presented him with a copy as a gift.
