Was just about to say. Because this was the first album in this direction of prog that I got, it was really special and stuff, but most of the stuff you mentioned are really weird to me too, the falsetto in Come Hell or High Water is probably part of what makes it my least favorite song on the album, I love the chorus though. Same for Spark of Archon, lovely chorus but that intro is fucking annoying.
Mute and Chromatic Aberration were easily some of my favorite 2015 songs though, I'll never get sick of those. Your Familiar Face and Passage are also on regular spins.
As for cohesiveness, that's definitely their downside, good thing I never really cared if songs were disjointed as long as I like the individual parts. Fossil Genera for example, or Mute/Chromatic Aberration.
