How to do Death vocals?

other question:

can anyone tell me here how to put that vibrato into the clean singing. For example like Warrel Dane from Nevermore...
Can you learn that or have I to be born with such voice?
Everybody can learn it i think, but i don't really know of any good teqnuiches. Just try, and try again. It shouldn't be that difficult.
 
If i can grunt,anyone can,but its hard to explain any technics.For exercise i do something similar to inuit throat singning.Dont try to be loud at first,i sound as deep loud or not.Dont forgot that youve got muscles while singning so 1 hour a day with a day or 2 interval is recommend at the beginning.With a lot of practice i can now hear two voices in one grunt.
 
Vibrato comes from years and years of singing. It must be natural; forcing it will just cause it to sound bad.
 
i do some fucking awesome death vocals.. i'm so impressed that i have to brag about it. . what i do.. is i dont talk like i talk.. what i do is that i talk inside my throat but like all the air from my stomach goes right there... dont know if im explaining myself here..

and you sound different if when you sing you open your mouth completely or jsut open it a bit..

if your mouth is dry .. youll feel horrible while doing it.. and in my case i sound horrible too..
