If you mean Inhale vocals which are used in grindcore can seriously fuck a beginners throat up and some will have to undergo surgery. Not saying all did, but the weak had too.

I heard someone say something about that. But then again, I don't know how to do any kind of Inhale vocals. I did try it several times, but I just ended up coughing lol.

Oh btw Splinter I fell for that lmao. I had forgot about it. -.-
