Decent album. As with their animation, you can tell Brian and popcorn's styles apart: B -> atonal, abstract, empty-valleys-in-space pieces; P -> upbeat poppy stuff.
Music was apparently written to match the videos (see Killscreen interview) & doesnt work as well on its own. The opposite was true for Skylark, which is indeed a better song.
Also, B's solo stuff was way better imho, both music and video; P kinda dilutes the feeling: C3DW entertains, B made you feel things, hence a "meh" album.
