Leitmotifs!
This is so you, haha. Lots and lots of loud hits and syncopated low brass, but that fits the sound perfectly. There is no real melody (progressive at least) to follow, which I'm OK with, because this is clearly an action cue. The intensity does not let up, that's for sure. Are you sure you're not Hans Zimmer?
The strings at 1:44 are well done, and the call-return style around the 3:00 mark is a nice addition although short lived. At five minutes this is quite a lengthy piece you have written, but somehow the drama is consistent (no doubt due to your skill and careful selection of the catchy motifs that are littered around). On second thought, some of these motifs are NOT catchy, but rather a utility for tension where it seems you have the percussion as the foremost driver of the action. Please excuse me while I pull my socks back up.
I can tell you had fun with this one. Once you have established a flowing beat everything else pretty much follows suit, like around 2:30 where you have a melody line ride over the insanity. Well done, fits the theme, but I am waiting for something a little more creative from you. Nice job on the mastering -- my only complaint is, and it may be because I'm listening at work on less-than-decent headphones, that the instruments themselves are centered too much in the stereo mix...because in a real orchestra of this size you don't have violins and trombones sitting (or standing) together...like at around :36 when the little diddy (the motif I hear throughout the piece) comes in (and is then quickly discarded as it evolves into sixteenth figures for the brass.). It's like, I'M DRUNK....oh wait, I'M FIGHTING!...but...I'm trashed!....but...cannon fire!
Good work Peter! More to come, I hope.
