If you’re reading this blog post, then it means you lived through the apocalypse. Congratulations. You’re probably in survival mode right now—scavenging for food, building out your subterranean bunker, fashioning weapons out of household objects, barricading your windows and doors from rioting looters and/or hordes of zombies—so I’m sure that rock music is far from the first thing on your mind. But let’s say you’re looking to set the mood for the current pickle you’re finding yourself in. Look no further for your Armageddon-soundtrack needs than today’s 12 O’Clock Track, “The Four Horsemen” by Metallica. What else would you listen to right now, R.E.M.?
