As we write this from Metal Insider headquarters, it’s snowing. Like a lot. And it’s not just up here in the New York area. All the way down to Atlanta is crippled under a heavy band of the white stuff, but the Northeast is getting hammered right now. So in honor of Black Sabbath starting a musical revolution 44 years ago today (more on that later), here’s one of our favorite songs by them, as well as a modern classic by Agalloch. Both are perfect music for watching a blizzard inside from. Be careful out there.
