I've tried and tried to appreciate what they were trying to do with the orchestral section of "Illumination Theory" but I just can't do it. That whole section, from about 7:10 to 11:10 (four minutes) does absolutely nothing to carry the song forward. There's nothing wrong with it in and of itself. It would be fine if they wanted to put something like that at on the album, between songs or something, but just shoehorning it into the middle of an epic serves no purpose. I might feel differently about it if the orchestral section felt musically (melodically, to be more precise) connected to the entire song as a whole, but it shares no common themes nor melodies with the song, at least not by design. The part is just kind of there...then it's....not there and using a reverse swell effect on each side of it doesn't necessarily integrate it into the song in a meaningful way or in a musically interesting way. Reverse swells. Welcome to basic audio engineering and mixing, class 2, maybe 3. It's a ham-fisted approach to production, sorry. It just feels lazy to me. Like they said "oh, we need an orchestral part to this, where do we put it?"
I actually think "Illumination Theory" was created from a couple of song ideas that were melded into one long piece, which is a pretty common and natural evolution. I just think they went off the rails a little bit with this part of the song.
That's really my only big gripe with the album. I "get" the album. I know what they were going for and I think they largely achieved it.
