Fithos... Lusec... Wecos... Vinosec...... Sephiroth!
Clearly, I can draw a parallel or three from different video game soundtracks (mostly Final Fantasy with a hint of Super Smash Bros.), but despite such influences you've really owned this particular genre.
As much as I love your use of intense chant-like vocals in this piece, I can't help but feel that those frenetic violin strings are still the standout performance. Suffice to say, it all comes together in a very epic way. I mean, I can't actually understand a word, but who cares? It's pure awesome and totally Boss Battle nostalgic.
You pull off a lot of tempo changes and ritardandos that I feel would be incredibly difficult with a troop of actual musicians trying to play and sing in sync. There's something kind of amazing in that knowledge that makes it feel particularly innovative.
The heavy-hitting percussion in the background serves to drive the piece fiercely, but you've also chosen some really poignant moments to drop it and bring it back in. On top of that, you've got some beautiful echoing celesta notes that ring along with what I can only assume is a harp for the early arpeggios. And finally, the track would never be complete without those resounding tubular or carillon bells.
I can honestly say that I've never heard a piece quite like this from you. I'm thrilled that you pulled something like this off so brilliantly, and have thoroughly enjoyed listening several times through as I penned this review. Simply fantastic, Alex! And best of luck in the NGADM.
