I agree. But apparently I have been told my claims require proof. It totally floors me.
But to humor him, I linked this:
http://en.wikipedia.org/wiki/Music_genre
"A conventional category that identifies pieces of music as belonging to a shared tradition or set of conventions". Now, lets analyze this: "shared tradition or set of conventions"... like a particular ideal a genre was built upon? Like the "shared tradition" of anti-Christianity in black metal? I think so.
Now, he says pieces can only be analyzed singularly based on the message or ideal of the one piece, which would invalidate the "ideology is a defining factor in determining genre". This is not the case. If a piece belongs to a particular genre, it must be analyzed based on the norms and standards its genre upholds. This is why, if you utilize realism in a painted piece you originally intended to be impressionist, it ceases to be impressionist. The two ideals, realism and impressionism, are diametrically opposed.
If you had asked me 5 or 6 years ago about "unblack metal", I would have told you it was black metal, and that it was actually sorta cool. But that was when I was relatively naive and unknowledgeable about black metal. How can you use an anti-Christian engine to preach a Christian message? It totally invalidates both the musics status as black metal, and the musics Christian message (
1 Thessalonians 5:22 "Abstain from all appearance of evil", which goes against black metal's anti-Christian sound and ideals). So not only do the black metal scene reject Unblack metal as being invalid,
so does the very religion itself.
