Some experimenting & training with his voice, how else? : p

Yeah I know but that's the grossest screech i've ever heard and I love it.

Based on what I like, only a few singers are able to do harsh-screams properly; it's the main reason why I detest metalcore/deathcore and all those core crap.

I find growling (mainly from melodeath artists) to be the best and a more suitable type of singing because you can actually distinguish the words and enjoy it. It all depends on how the growls are done too.

All-in-all, yes I'm difficult as fuck when it comes to singing.
