I'm interested to see how the vocals would fit
I consider myself a pretty seasoned, creative musician and I cannot possible see any conceivable way vocals would fit over this and sound good, unless they are used sparingly. So, we'll see how it turns out. Honestly I think this song is intense enough to stand on its own. I voted 5/5 and 10/10, but really it is a 9.5 -- no song is ever a 10/10 :P
