I know Sune Martin personally. Very cool guy. He got the Harpa award in Cannes last year for his score to the excellent Danish film LAND OF MINE. I'm guessing this will be in a similar, dark landscape -- given the subject matter.
I think it's only been screened in Venice (my colleagues have seen it there). Will take a while before it premieres on Netflix or selected theatres. I'm assuming a soundtrack will be released at the same time. But it may also very well not receive anything.
