After the phenomenal critical success of the first two volumes of the complete Sibelius symphonies (Gramophone Editor's Choice, Preis der deutschen Schallplattenkritik, Diapason d'Or, FFFF Télérama etc.), the Finnish conductor Santtu-Matias Rouvali and the Gothenburg Symphony Orchestra introduce us to the 'green' side of Sibelius who, suffering from health problems and financial worries, moved to the shores of Lake Tuusula just before writing his Third Symphony. His output was powerfully inspired by nature. In April 1915, when the world was in chaos, he wrote in his diary of the appearance of sixteen swans over the lake and noted down their cry, which inspired the great horn theme of the Fifth Symphony's finale.
