Residentie Orchestra
During the years after World War II, from 1949 to 1973,  Willem van Otterloo was the chief conductor.  They gave regular concerts in the Hague and in Amsterdam and made recordings for Philips Gramophone.  Van Otterloo introduced them to many different styles of music.  As in its earlier days, the orchestra often played modern music conducted by the composers: Bruno Maderna, Mauricio Kagel, John Cage and Pierre Boulez conducted their works.  Recordings were made with other conductors including Gennady Rozhdestvensky and Evgenii Svetlanov who included music by less well-known Russian composers.
