“Conducting is a good profession to grow old in, because it’s always a challenge, and you need challenges when you get older,” said Herbert Blomstedt, born in 1927, who is continuing his long-standing collaboration with the Berliner Philharmoniker with undiminished energy and vitality. On this programme Sibelius’s dark, mist-shrouded Fourth Symphony is contrasted with Brahms’s Third. Between them, a rarity will be heard: the solemn Intermezzo from the cantata Sången (The Song), composed in 1926 by the Swedish late Romantic composer Wilhelm Stenhammar.
