OOOOOOH! I love that distortion on the synth, holy cow! There's something about fuzzy synths with heavy reverb that just gets to me.
And the bridge that opening portion goes into, it reminds me of the soundtrack of Pocket tanks, which I loved playing when I was in high school. It's so cool that you could take such a dense intro and drop it into such a finely minimalistic melody.
Then, you just incrementally make the whole production thicker and bigger and more dynamic. Your drums just hammer away at my soul, in a good way, and the way those synths wail around 4:00 just oozes emotion, man.
And then it eases itself out so smoothly. I personally find it hard sometimes to take the momentum out of a large track without it sounding too sudden or too long-winded, but your use of reverb in the outro really hits the nail on the head.
I really, really enjoyed listening to this. Powerful blending of sounds and effects channels, emotionally charged percussion, and an ideal amount of time for the song to grow and evolve in a natural-feeling way.
One more thing. Did my own songs really inspire your use of beeping sine waves? If so, I'm honored, haha.
