Finally listening to this and paying attention, it's really an even better track than I realized during the fight.
Leif Chappelle has done an amazing job, especially when it would be so easy to try and ape Jeremy Soule and just call it a day, though I think the quality would be noticeably off. That's not an insult to Chappelle, just that any time one artist mimics another it rarely feels genuine. The last time I can remember being impressed with an obvious emulation was Michael Giacchinos' "Jurassic Park: The Lost World" game score which isn't just pretending to be John Williams, but almost gets to themes he wouldn't do until later(that first theme for the compy is creeping into Harry Potter territory Williams wouldn't get to for almost another 5 years later). But I digress.
The post-launch music has all been really solid (crazy guitar noodling for the Nightmare Tower trailer aside, but that's just because it stands out as so different). Soule did a respectable job giving each race a sort of thematic tone that spills out into their respective regions without harping on a single leitmotif, and I think they've done a solid job of keeping that approach with the Living Story. Scarlet does have a theme, and it does play in short little twists in each track, but it's more a general bombastic/menacing tone that runs through each of them, without the fluttery fantasy notes that Soule would have had.
I guess what I'm saying is, it's not Jeremy Soule, but that's goodbecause any attempt to emulate him would only be an obvious imitation and because Scarlet's story needed something less his style and more like what we actually got. For example, there are parts of the Marionette theme that are clangy and metallic that seem more in line with Brad Fiedel's Terminator score, and that's something I just can't see coming from Soule.
TL;DR: Damn that music is good. I feel like I'm still digesting Breachmaker, but I know good when I hear it.
