Sick synths. I've tried to do that myself once a few years ago and failed so I've never returned to it. What did you use for the low, deep, rhythmic sounding synth?
I liked the build up in this one, from something a bit menacing to FRANTIC at the end. It produced well and sounds coherent. I was impressed with the change of rhythm at the end too.

Finally... THANK YOU for using dynamics effectively.

I love the ominous mood at the beginning. The subtle pause at :11 is a nice touch. Drums are nice and crisp, and the mix is loud and clear. I like the more mellow section at :50. Organ synth at :54 was cool, and the melodic riff at 1:05 is pretty great too. The build-up into 1:51 was a little drawn-out and broken up, but I think my main complaint is with the superfluous 2-second transitory section at 1:48. After an already very dynamic build-up, that section seemed more confusing than anything else to me. I guess I was also a little thrown-off by the sudden injection of so many new harmonic elements at 1:51. It's a fitting bridge in a lot of ways, but I suppose at that point in the piece I was expecting a final refrain that was a little more in-line with some of the other themes and riffs of the piece. At the same time, I applaud the way you created variety across the piece as a whole. Saving the most dramatic and, in many ways, most melodic section for last is probably smart. Maybe I just didn't listen closely enough, but I think I would've liked to see some of the riffs featured in the last minute foreshadowed a bit more earlier in the piece. Obviously, you intended 1:51 to be punchy and jarring to some extent, but the transition there didn't quite work for me somehow. Anyway, I'm rambling about tiny compositional details. Overall, really strong work with the production, sound design, atmosphere, and thematic elements. Keep up the good work, Spadezer! ^_^
