I finally went and read the article now that I had the time. It's a fairly interesting read, although the little hair I have on my head rose as I was reading More than three decades after Black Sabbath conjured images of the dark arts, heavy metal is growing up. That's a direct attack on one of our main classics music and content wise and I fail to see how a generalisation like that can still make it into critical journalism. Especially if you carry on a few paragraphs down by saying Heavy metal has always touched on social and political issues. Metal grandfathers Black Sabbath criticized the Vietnam War in songs like "War Pigs" and "Children of the Grave."
Kudos to anyone who can convince me how those two lines fit together nice and well in one and the same article, both of them coming from the same hand.
Generally speaking it's probably true kids can do with a bit of a push in the back when it comes to global awareness. However I have the instinct of stepping up for the one who's being talked down and the same goes for this article. I don't feel there's anything wrong with a bit of innocent entertainment. Not even with a bit of less innocent entertainment, for that matter, as is sometimes the case with metal, ha!
