theme song?

I saw the movie at the Copenhagen Film Festival last year, and I liked it. Although made for television it has a strong visuality and some images you definitly won't forget easily.
But my question is: Does anyone know the title and the composer/band of the theme song? If I remember it right it is not just played in the end of the film, but also during the film (or it even is part of the plot).
Any help appreciated!
