He became principal music director in Augsburg in 1954, and in Bremen in 1955, concluding in both posts in 1960.^[3] In 1957, he recorded a scene from Wagner's Lohengrin, with the Philharmonia Orchestra in London and the singers Elisabeth Schwarzkopf and Christa Ludwig, under the production of Walter Legge.
