Henri Paul Julien Dutilleux was a French composer of late 20th-century classical music. Among the leading French composers of his time, his work was rooted in the Impressionistic style of Debussy and Ravel, but in an idiosyncratic, individual style. Among his best known works are his early Flute Sonatine and Piano Sonata; concertos for cello, Tout un monde lointain... and violin, L'arbre des songes ; a string quartet known as Ainsi la nuit ; and two symphonies: No. 1 (1951) and No. 2 Le Double (1959).

George Szell, originally György Széll, György Endre Szél, or Georg Szell, was a Hungarian-born American conductor and composer. Considered one of the twentieth century's greatest conductors, he was music director of the Cleveland Orchestra of Cleveland, Ohio, and recorded much of the standard classical repertoire in Cleveland and with other orchestras.
