The piano in Akt 2 gives me the chills. I've listened these tracks a few times, and I can say they're very memorable. You have striking melodies rising out of a unique dissonance. Using so much disharmony was risky, and I think you pulled it off fantastically by using a great arrangement and having repeating motifs.
This was extremely surreal and evoked otherworldly imagery that's usually difficult to conjure up with such a minimal arrangement of acoustic instruments.
