Tom Service explores the music of Sibelius as a force of nature with 'Wild' writer Jaye Griffiths.

The inspiration for Sibelius's Fifth Symphony - the famous flight of sixteen majestic swans across the lake from his house north of Helsinki was, in the composer's words 'one of my greatest experiences. Lord God, that Beauty...' It's a well-known story, but in today's Listening Service Tom argues that Sibelius's music isn't just a prettified depiction of nature, it's a wilderness itself, with its own teeming, wild ecologies: from the pagan creationism of Luonnotar, to the primeval forest gods of Tapiola, and the elemental forces of the Oceanides.

With writer Jaye Griffiths on wilderness as freedom, listening to a woodlouse, devotion to absolute life, and silence as extinction.
