Obviously I've got an idea of my own (concerning that question) but reading different opinions and perspectives is always interesting and can be eye opening (although I swear, mine are open right now, I'm not THAT good around my keyboard) (apologies: I love horrendous humor). Here's an objective argument that could at least settle the matter somewhat and get this topic going: of the now many decades of metal we've had, 80's til the 2010's, all the "classics" are very widely considered to be the better albums of the earier decades, not the latest. A legendary monolith of metal is Morbid Angel, Metallica, Iron Maiden, Cannibal Corpse (love em or hate em personally, that's a fact) - NOT Tesseract, Braindrill, or Animals as Leaders. Some would answer they haven't had the time to gain 'legendary status', but I still push the argument I don't think that's what's going to alter the equation, the first batch are clearly legendary, the second (contemporary ones) feel more 'experimental' if anything. Like their experimental prowess is praisable - but not legends. It seems it's quality (older bands) vs experimental/technical exploration (newer). What d'ya think ?
