Hellion Sounds albums never credit any artists specifically, so I'm quite curious how it was figured that Eru solely arranged this album. Track 9 is definitely his, as he posted that one on his site, but as far as I can tell, everything else is fair game for
the mysterious entity that is Hellion Sounds.
Were I to speculate, I would put a conservative lower bound on the number of arrangers at three (Eru, S.S.H. or someone who's trying to sound a
lot like him, and whoever did "Plain Asia").
