considered a pioneer of the musique concrète genre of electronic music. Between 1949 and 1958, Henry worked at the Club d'Essai studio at RTF, founded by Pierre Schaeffer. During this period, he wrote the 1950 piece Symphonie pour un homme seul, in cooperation with Schaeffer; he also composed the first musique concrète to appear in a commercial film, the 1952 short film Astrologie ou le miroir de la vie. Henry has scored numerous additional films and ballets. Among Henry's best known works is the experimental 1967 album Messe pour le temps présent, one of several cooperations with choreographer Maurice Béjart. Perhaps one of Henry's most well-known influences on contemporary popular culture is the theme song to the TV series Futurama. The tune is clearly inspired by Henry's 1967 song "Psyché Rock."
