From its expansive opening to its transcendent climax, Sibelius’ Fifth Symphony is one of the most vivid orchestral works of the 20th century. Finnish conductor Hannu Lintu, in his CSO debut, pairs this with the composer’s best-known work, Finlandia. Pekka Kuusisto performs Nielsen’s spirited Violin Concerto. “Nielsen was a folk fiddler and Kuusisto made it show in the gorgeous looseness of his rhythms and stripped-back grit of his sound” (The Guardian).
