Man that intro is pure evil! You sure are good at those kinds of reverse effects and the whole darkness vibe. It's weird because it's light and heavy at the same time.
It really switches up right before 3 minutes but still flows. That sound around 3:50 is really cool. Not sure what to call it but it sustains and it's really washy- awesome. You're good at introducing new sounds. Love what you did with the piano. Nice and creepy. The beat is subtle and also awesome.
I'm glad I'm not listening to this alone in the dark during the witching hour! Otherwise I'd be pretty spooked and maybe start seeing ghosts and sh*t.
