We seriously need more stuff like this out there. There are a few thing to take point on, though. Some of the frequencies are interfering with each other here, causing sound-dips between instruments. While the overall music is excellent, and the concept novel and very unseen here on Newgrounds, either better sound management is desirable, or a better sound-processor on your side. I'm using an expensive pair of SoundBlaster headphones, so I know it's not my end.
Either way, dude. Keep it up. I'd like to see more of this kind of independent art on Newgrounds in the future.
