Not a problem at all, I said so myself, it's kinda extreme to use the bass voice in the original key. It's been fun though because I rarely get to use that part of my range. If you still want to mix it up with two different voices I could do the bridge parts an octave up (I will prepare a demo as soon as I can). Otherwise I'll only do the low almost spoken words backgrounds in verse 3, like you wrote on Skype.
Oh and interesting vocals style TheAtliator, with a few extra helpings of drama, expressiveness, and vibrato.
I know it's only a quick demo but I'd suggest toning it down a little in that department for a song like Disappear. It's about facing the inevitable, finding strength for someone in a situation where your strength seems all but spent, its inescapability causing an overload that almost leads to emotional shutdown, leaving feelings awkwardly paralyzed, uncomfortably numb, so to speak. I think a more subtle approach without overexpressing the pain would be better suited for the song and its impact.
Looking forward to the next steps and the first results!
