I like very much the first part, a little bit ambiguous. I don't know if you follow here a sort of music form or if it is music that goes on and on. The rhythmic pattern is constant the whole piece. Although it is an element that unifies, perhaps it's too much time with the same rhythm. Several climax are well constructed. It's nice.
The music is dramatic and it reminds me of a requiem in a film. However, I think you really need to work on your sampling with sounds. There is still a lot to gain for you.
I like the drama.
Thanks for the feedback.
My thinking with the vocals was that it adds a more industrial vibe by having factory workers chanting but I do see where you coming from with them sounding a bit out of place. I think I might experiment with altering the reverb on them and maybe using different samples to see if I can blend them in better.
