I laughed while reading the article, as if listening to David Bowie with the lights off, the bathroom door locked, and £12,000 speakers will somehow unlock a deeper artistic meaning in classic butt-rock. Doing the same for metal would strike me as equally ludicrous. Yes, metal at its best is beautiful and complex, but just as importantly vicious, savage, the sonic equivalent of Conan the Cimmerian. Best enjoyed with a beer, copious headbanging, and whatever speakers do the job.
And lol @ people trying to compare their music to Dickens or whatever ye olde writer they choose. Insecurity much? Besides, I can see no joy in reading a Dickens novel from front to end in one sitting. I doubt the Victorians did either, as many of his major works originally appeared serially.
