Can someone explain the concepts of sub-genres to me?
It seems like if 2 bands do not sound the same they get their own sub-genre which, to be honest casts a very bad light on the entire metal genre.
It's just convenience.
Super extreme cases aside, like Post-Technical Deathgrind, Melodic Black Metal, there are some fundamentally different strains of metal music.
Would you say this
sounds anything like this?
This is the reason the "sub-generes' exist. Really, they are simply descriptors that help when having a discussion about said bands and create and ease of use when looking for new ones.
"Check out this new band I found last night."
"Cool, what do they sound like?"
"Really happy and fast."
That description could be a bunch of things, within metal, it would primarily be some sort of power metal band.
Let's take it further this time.
"It's a power metal band."
Now they have a very wide and general idea of what the band is and sounds like. Granted even within power metal you have a lot of diversity depending on the band. Some PM bands aim for a very light and neo-classical sound, with the guitars somewhat lower in the mix and the keyboard takes precedence. There is also more 'meatier' power metal that relies more on hard and heavy guitar riffs.
Anyway, let's say this
"They are a power metal band with some death metal influences/tendencies."
This could mean a few things. Most usually it indicates that the singer uses a deeper or harsher vocal style as opposed to traditionally sung power metal.
That person now has a slightly better understanding of what they band may be like and whether or not they want to invest further time and effort checking them out/buying CD's.
But no it's not true that any band that sounds different get's there own sub-genere.
That is where this system gets abused.
No, just because a band uses an old style synth amongst a traditionally hardcore backdrop does not mean it is "NES-core".
