I'll second Black Sabbath. But then I'm an old fart. I just have to be able to understand the lyrics. All this grunting, hocking up loogeys and such. I just don't get it. Bands like Sabbath, Iron Maiden, Judas Priest, Dio have been ther and done it. The music is and always will be good. Metal like any other form of music is proven by it's timeless nature. We'll see in twenty years if any of the latest crop are still selling records. As much as I hate Lars, Metallica has been around the block a few times and are still here. They've just grown up, not sold out.
