The waves caused by Jean Sibelius’s music came ashore both in England and in the USA. Samuel Barber’s one-movement symphony, in the spirit of Sibelius’s Seventh, was written in 1935 and soon travelled throughout Europe as an example of the expressive power of American music. Ralph Vaughan Williams dedicated his work to the Finnish master without asking permission but, after hearing the symphony, Sibelius was full of gratitude. Pianist Olli Mustonen interprets a concerto by his composition teacher, which again moves in its own, ethereal dimension.
