True Nordic Crimes

I've recently been watching the series True Nordic Crime on Prime Video. It's interesting especially considering the stereotype of Iceland being a sleepy, safe and quiet country. Yet humans live there, and humans commit crimes so there's no reason to believe that Iceland is some crime free utopia. It is not as vivid and lurid as an American true crime series which I don't mind. The show is a documentary and that is clear in terms of the production. What I've been trying to find out what is/ who performs the theme music to the series. It seems to me that the theme is almost exactly like the music in the song "Over" by Portishead. That opening guitar/bass lick is almost note for note to that song. Anyone know the answer to this?
