Thank you for the analysis. Unfortunately, from the perspective of "Solar Metal", those two tracks are the night-time tracks of the album (the night before the battle, and the approaching twilight after the fall of the last man), so I had to give them something of a more lunar nature to reflect their contextual/thematic meaning. The rest of the tracks (and parts of the reworked track eight) are less "eerie" (good way to put it) and more triumphant, moving to outright barbarous towards the end (as the tide of the battle shifts).
The ending has to be in Berzerker mode, given the context, but tracks 2-5 are much more "reflective", though I'll take into account what you've said about Summoning and see if I can't improve those songs by cutting down on the number of instruments playing at diminuendos in the songs. My compositional desire has always been to just keep adding stuff until I have every note that fits playing at once, which isn't always the best idea.
