In 1946, influenced by Surrealism and René Daumal, he founded a literary journal titled Les Cahiers Sensationnistes.

[1] During the 1950s, he produced many radio plays based on French writers, with a preference for Surrealists like André Breton, René Char, Jean Cocteau, Antonin Artaud, Julien Gracq.

[2] Almuró used increasingly difficult and provocative texts for his radio plays, like Jean Genet's homoerotic poem Le Condamné à Mort, for which Almuró created electroacoustic music in 1952, or Antonin Artaud's Van Gogh, Le Suicidé De La Société in 1958, a text written 1947, the same year as Pour en Finir avec le Jugement de Dieu [To Have Done With the Judgment of God], written for radio but withheld from broadcast by directors in 1948.

[3] When Schaeffer founded his Groupe de Recherches Musicales in 1958, Almuró joined as a member for several years, but soon launched his own, independent recording studio in the early 1960s.

Almuró's cinema is overtly homoerotic and has been described as "un cinéma d’orgasme et de désir entre deux hommes" (pleasure and desire between two men) by French film director Christian Lebrat.
