I found this in a .zip file of Emiya remixes on an obscure tumblr somewhere, and somehow this does not appear anywhere else on the internet. Or at least, the words in this title do not in relation to the music. So I took matters into my own hands and forced it into existence.
What this appears to be is some kind of techno/trance remix combination of either the Church on the Hill track or Angra Mainyu track with Emiya. It’s pretty cool.
