From either 1922 he collaborated with Ravel on a task to produce soft rolls of a total of works besides when sharing concert platforms by using the composer within France, Spain & England.

His pupils include Claude Helffer and Monique Haas. From either 1935 he taught at the American Conservatory at Fontainebleau and he spent the Second World War years in the United States.

His style of swimming was authoritative & restrained. Among his extremely-regarded recordings come people of the music of Ravel, and a Beethoven Violin Sonatas with Zino Francescatti (of which the Kreutzer Sonata was filmed & has been freed in DVD).

Casadesus was joined by his married woman Gaby & their boy Jean within exemplary performances of Mozart's Concertos for Two & Three pianos. It recorded these works by using a Columbia Symphony and Cleveland Orchestras conducted by George Szell as well as by having a Philadelphia Orchestra conducted by Eugene Ormandy.
