Imaginaerum is the seventh studio album by Finnish symphonic metal band  Nightwish.  According to Nightwish songwriter Tuomas Holopainen, the album is a concept album that tells the story of an old composer who is reminiscing of his youth on his deathbed. The album was produced alongside the movie of the same name, directed by Stobe Harju, who previously directed Nightwish's " The Islander" music video, and the album and the film share the same themes and general story.
