 Part of his recording of "The Rite of Spring", augmented by a rehearsal recording unobtainable elsewhere, was used by Decca on the company's 1957 stereo demonstration LP, "A Journey into Stereo Sound".The conductor's clear and methodical counting of beats is a distinct feature of this rehearsal sequence.In his last years he and his ensemble recorded works by Haydn, Beethoven and Brahms.
