looks like it could be an interesting film- score by Icelandic composer Johann Johansson who has done a couple of great albums (Englaborn and Fordlandia to name a couple)
"An elegy in film and music to the coal mining history of North East England, and a unique creative collaboration between the renowned American filmmaker Bill Morrison (Decasia) and acclaimed Icelandic musician and composer Jóhann Jóhannsson.
Created from archive and newly-shot film footage, The Miners Hymns celebrates the sense of vibrant community, rich, self-organised culture and the forbearance that characterised the lives of those who worked underground, and the places in which they lived. Accompanying Morrison s filmic collage, Jóhannsson s newly composed modern classical score draws upon the region s brass music culture: image and sound combine to create a rich homage to Britain s coal mining heritage."
