.There is metal that is "stereotypically" prog metal a-la Dream Theater and I consider that to be "prog metal." Progressive ______ metal is something else entirely, depending on what is in the ______ space. Prog metal is a definite genre.
Well, you could go even further and say that death metal is derivative of thrash, as is power metal, and that doom metal is derivative of heavy metal, and go like:I would say it's a description as well, for the most part.
I think it comes down to these genres:
Heavy Metal
Doom Metal
Power Metal
Thrash Metal
Death Metal
Black Metal
All other genres are derivative genres of the above imo.
heavy metal
thrash metal
black metal
and then you could say that thrash is derivative of heavy metal, as is black metal, and just say
heavy metal
but then you'd be a fucking retard because trying to fit everything into broad categories is a waste of time.
With regards to power metal, I'm loving Luca Turilli.
