Oh hey, I studied physics in college, lol.
I've always admired the creativity and patience it takes to make drum and bass, dubstep, etc. music that's chaotic the way this piece is. The density of musical ideas involved isn't something I feel I've ever managed to achieve... so it's kind of funny to me that even as I appreciate that here too, I'm finding myself wanting even more kinds of FX and flair? I loved that little delayed arp at ~0:54, and the drum fill with the toms JUST before the drop felt perfectly placed, and I wanted more like that. Like this piece sounds super unique to me as it is, I guess I would have enjoyed more of the variation of the piece being in timbre too?
Is it me or am I hearing a frequency gap between your sub bass and the body of your bass? I can't pin it to a specific frequency range beyond that I would have loved to hear a richer/warmer/fuller sound, even if marginally more so? (Or maybe the richness isn't coming through to me because of something in the mix? Or the headphones I'm listening to this on?) I really enjoy the sections like 0:54 where the bass gets a bit wilder — it's actually growing on me each listen — and I feel like I'd love it that much more if you pushed the wall-of-sound effect even further still.
Last little nitpick, the snare feels a little trebley to me? But that's just my preference I think. In general I've never tried to work in this genre myself so I'm not sure what are stylistic choices vs possible places for improvement — like maybe the relative sparseness I'm hearing at 0:22 up to the drop was meant to create an atmosphere or tension that would make more sense if I listened to the genre more. It makes me wonder what music/artists influenced this piece.
That's all I have I think! I had fun listening to and reviewing this :)
