In the 1920s and early 1930s he often worked with the London Symphony Orchestra. He made gramophone recordings in the very early days of the gramophone. These include Scriabin's "Poème de l'Extase" and many bits from Wagner's "Der Ring des Nibelungen" and (in 1925) the complete "Symphony No. 9" of Beethoven. He was the conductor for the first recording of Rachmaninoff's Piano Concerto No. 3, with Vladimir Horowitz as soloist.
