Slayer’s Reign In Blood, released October 7th, 1986, lands smack in the middle of that decade like an axe hitting a bullseye. No other metal release that year or during that era felt quite as demanding and insurgent. It hit fast — clocking in under less than a half-hour in its original release — and hit hard, helping push a band that was already respected among their fans and peers toward new levels of success. A spot on the Billboard 200 chart. Gold-certified sales. Bigger concert dates. And a level of inter-band tension that wouldn’t settle down for the better part of 15 years.
