André Cluytens has been played on NTS shows including Slime w/ Little, with Gaspard De La Nuit first played on 23 July 2017.

André Cluytens was among the leading French conductors of his time. His father, Alphonse Cluytens, was also a conductor, and recognized the boy's musical talents. André was enrolled in the Royal Flemish Conservatory at the age of nine. He studied in the piano class of Emile Bosquet, and received first prize for piano at the age of 16. The next year he won first prize in harmony, theory, counterpoint, and fugue.

His father was conductor at the Royal French Theater of Antwerp. André became his assistant and a choirmaster there. When an illness prevented Alphonse from conducting, André made his performance debut in 1927 in Bizet's Les Pêcheurs de perles. After that experience he devoted his efforts to orchestral and opera conducting rather than choral work, and he became a resident conductor in the house.

In 1932 he accepted a position as the musical director of orchestral concerts at the Capitole de Toulouse, and he became a French citizen. In 1935 was appointed the opera director in Lyons. He was an assistant of Josef Krips in a summer series in Vichy and, once again, was called on to substitute when that conductor could not perform. He became musical director of the Lyons Opera in 1942, conductor of the Conservatoire Concerts and the French National Radio Orchestra in Paris in 1943, and in 1944 conducted at the Opéra de Paris. From 1947 to 1953 he was music director of the Paris Opéra-Comique, and in 1949 was appointed as principal conductor of the Conservatory Concerts. He retained that position for the rest of his life. In 1955 he was invited to conduct Lohengrin at the Bayreuth Festival, the first French person to appear on the podium there. He debuted in the United States in 1956, and in Britain in 1958, when he substituted for Otto Klemperer. He formed a close relationship with the Vienna State Opera, which he first conducted in 1956, becoming a permanent guest conductor in 1959. In 1960 he became conductor of the Belgian National Orchestra in Belgium, also holding that post until his death. He also formed a close link with the Berlin Philharmonic, with which he made a notable recording of the Beethoven symphonies. However, he was primarily known for French repertoire, premiering works by Françaix, Jolivet, Messiaen, Milhaud, Tomasi, Büsser, and Bondeville. He was invited back to Bayreuth in 1965.
