In 1925 he became second conductor of the Concerts Pasdeloup, greatly extending his work in purely orchestral music (including an appearance at the Royal Albert Hall, London in 1926); he later served as head conductor and director of the Pasdeloup from 1934–1940. From 1928 to 1934 he became principal conductor of the Orchestre Lamoureux. He notably conducted the premiere of Roussel's 4th symphony (which was dedicated to him) with the Orchestre Lamoureux in October 1935; he had previously made the premiere recording of Roussel's 3rd symphony with the Lamoureux. In 1938 he was twice a guest conductor at the Bergen Philharmonic Orchestra; in 1947 he conducted the same orchestra with Geirr Tveitt in a recording of the latter's 3rd piano concerto. He also conducted a radio performance of his own flute concerto with Per Wang as soloist with Oslo Philharmonic Orchestra on NRK.
