Between 1958 and 1965 the Decca record company made the first complete recording to be released of Richard Wagner's tetralogy, Der Ring des Nibelungen. Of the four component operas, there had been two previous studio recordings of Die Walküre, and a monaural radio recording of Götterdämmerung, which was released on record in 1956, but Decca's was the first Ring cycle planned and recorded for the gramophone.
