First of all, this is wonderfully engineered. The samples, mixing, everything is on point. It never feels too crowded. On the composition side I think that I can’t add a lot to what was said before.
I personally would associate it more with some « dark », maybe deranging stuff (possibly because of that guitar). It wouldn’t make me think of dark matter if you hadn’t mentioned it, but it’s such an abstract and new idea that nothing would probably make me think of it.
From a soundtrack point of view : depending of the what the scene conveys, if a feel of growing danger/tension matters most etc then it could be action music as well (I’m thinking about a few scenes in 28 weeks later or inception).
I like it a lot, it’s a joy to listen to and there are moments after the initial buildup that really speak to me. Great work!
