If crafting a soundtrack that deserves to be heard on its own is challenging, surely doing so for a documentary is even tougher. Most dramatic films, after all, want a score to boost and multiply the emotions portrayed on screen, whereas documentaries for the most part try to make their points with..
I saw this documentary a few months back and I remember saying to myself 'Wow, this soundtrack is excellent. I wonder who it is?' and being struck when I saw Simko's name. Certain pieces bear the influence of the spectral school of 20th century composition, but definitely don't sound anything like the stuff I've heard from her previously.
Not sure how it sounds isolated, on an album, but the soundtrack works very well with the film.
Also- the film itself is a lot more interesting than a doc about particle accelerators and scientific one upmanship might sound to a layman. Check it out.
