Furthermore the author alarms that "if metal doesn’t change to reflect its more diverse audience, it could vanquish itself into irrelevancy", and thus very much hits the nail on the head regarding what should concern heavy metal artists and fans alike: inclusiveness (the topic of inclusiveness also happens to be very dear to ulbator). In the same paragraph, we learn that failing to be more inclusive would have devastating consequences for heavy metal: "Keep excluding women, and it will be a dead genre in 50 years — or an outdated, embarrassingly nostalgic subclass of musical racism and sexism." Because avant-gardeness, political progressiveness and "privilege" concerns must be no. 1 on heavy metal's priority list, right?
"this year's Rockstar Mayhem Festival hosted 13 bands", it turns out. But wow, just wow: "no female musicians were on the main stage". Oh dear, oh dear.
