Hello. I�m here requesting this soundtrack. I don�t have any info on it, and I find it strange the fact it hans�t been officially released yet.
I found it a nice (non-realistic), thriller/drama movie. Sad to see so few info about it�s OST, which I think its fantastic, it really captures the essence of Siberia and the north sea.
Here�s a picture of the poster:

It's up to the studio whether to release it or not, and until they do, it's going to be pretty hard to get a hold of. This is the best I could find for now: https://www.youtube.com/watch?v=pPLckxnNWwY
