The beginning was SO GOOD! The vocal samples, the intensity and tone, the way they repeat and splice together... perfection.
Then that unconventional dub/chipstep kind of beat kicks in, after the build, with the somewhat off-beat string kinda pattern and eh... I'm not as big a fan of that.
The other part's SO GOOD! The vocals are just perfect. I wish the sections between them would be different, equally fluent and atmospheric, those middle sections break the spell for me a bit. It may be the pauses are just too long. It doesn't flow to me. It feels abrupt.
Creative track though! It's unconventional all way. Sometimes in the best way possible, sometimes... less so, IMO.
Keep up the good work though! Almost perfect.
