It seems that more of you have dont understand me.
If u are saying that u havent listen so much death metal bands, how can you define death metal???
Maybe for some people screaming and making gutural voice its not agressive but for music it is. You say that Led Zeppelin and other persons are heavy because they put feeling in their songs, u ar right, but remember that feeling is a relative thing to each one. Hear Old Metallica, Death (last days), Helloween, Overkill, (old) Anthrax, Sodom, Overkill. His voices are not gutural but are agressives, u feel the agression, the rage, or whatever its trying to comunnicate to the person is listen.
I dont know what programs of metal have u listen but gutural voice is not the only thing in metal, in early death metal agression was ALL. even now the "old school death metal" is pure agression, they have no great technique and have no raw production. His words say it all "Brutality comes throught simplicity"
And sistem of a down its not metal
