Feels like I'm falling into a trance here. The combination of the rough experimental sounds plays well with the very smooth bell tones. I'll disagree with @Noisysundae here though, I feel like the "empty" sections are an important part of the song and lend it some character, as well as making the other sections impactful. Beautiful piece!
Edit: @Noisysundae contacted me to explain what he meant by the emptiness. I'll agree with him now that having some more supporting instrumental voices could help elevate this. I still think it stands well as it is, however.
