Other non-U.S. composers that Bernstein championed to some extent at the time include the Danish composer Carl Nielsen (who was then only little known in the U.S.) and Jean Sibelius, whose popularity had by then started to fade. Bernstein eventually recorded a complete cycle in New York of Sibelius's symphonies and three of Nielsen's symphonies (Nos. 2, 4, and 5), as well as conducting recordings of his violin, clarinet and flute concertos. He also recorded Nielsen's 3rd Symphony with the Royal Danish Orchestra after a critically acclaimed public performance in Denmark.
