Peter Jackson hired Crowded House frontman Neil Finn to write and record an end credits song for The Hobbit: An Unexpected Journey, and you can hear the resulting tune below.
Song of the Lonely Mountain is a mournful multi-layered piece replete with angelic vocals, clashing metallic blasts and a determined-sounding build, which captures the feel of an arduous journey.
Speaking to Rolling Stone, Finn revealed that the song was directly inspired by a vocal melody that is heard in the film. He said: "The Song of the Lonely Mountain was developed from a dark and mysterious theme which the dwarves sing early in the movie.
“After some days of mining underground (actually, in Peter’s office) I emerged with the song, then set about recording it with my sons Elroy and Liam. Dave Fridmann came in at the end with a bold mix. He seemed to respond well to my demands for 'more anvil!' Pop music needs more anvil!”
