Re: If I fail as a drummer? I can...?
Wow! Didn't expact that at all; I was expecting screams. That's some serious gutteral thing you've got going on. The question is if you can get the required volume and extreme vocal stamina required to get through a gig, but if you can I say go for it.
The tone reminds me of Mikael Akerfeldt from Opeth, or a couple of the guys from the Norwegian black metal scene. Good job!
