The first drum beat got my attention - the drums and percussion in this are awesome! the female vox are incredible.
not fond of the demon growls - I completely understand what you're trying to do and I'm sure I'm wrong, but I'd like to hear something a little different there. to me it just doesn't seem quite right. not saying that it doesn't need the growls, just something not quite what it is...
other than that this is really great! love everything else about it!
