You do have to understand that anus.com is neo nazism, is that good or bad? Thats for you to decide. As for black metal bands being dead, it depends what you interpet as black metal these days, and who you ask.
Yes many of black metal bands that do come out today, are not 100% black metal, they are like the article says, copies. To be 100% black metal, you have to have feeling. For instance I can listen to bathory 24/7 but I can't listen to Nile at all (Yes, I do consider Nile as a black metal band, if you beleive im wrong, each to his own I guess). Why? I dont feel the black metal I feel from bathory as in Nile. That or I just dont like the band period. Who knows.
As for that dimmu hoodie comment and mayhem...I will never understand why people wear anything of the bands...the band does not make any money off this merchandise, and if they do, then they are what you hate...sellouts (i'm not calling any band a sellout, this is just a term most people here use describing what I just wrote previously). As for the excuse of "publicity", generating a bigger crowd for that specific bands concert...In a way thats redundant considering you don't wish those people to be with you in the same concert, considering yes they are posers if they saw your bands t-shirt, they bought one album and they think they worthy of going to that bands concert.
As you can see in my last statement, i said worthy of going...I beleive those who do attend a bands concert should be worthy of seen a band live, not just because they bought 1 or 2 albums, or they know the guitarists name or whatever the reason maybe...this is just my opinion. It might sound stupid to some. Maybe im trailing off here, but I hope some get my point.
