Oh ****! Thanks for reminding me.
66(6). Slayer - Reign In Blood - (1986)

Everyone on Earth with a sack has heard this album, and with good reason: it's the Thrash Bible. It's everything that thrash at its most basic ever was or ever tried to be; not because it came around and just summarized everything that had come before it, but because it blazed the thrash trail so definitively that nobody else really had anything left to add. Wasn't much left to do after that but go death metal. From those first blazing riffs and hideous shriek, to the crack of thunder and falling rain at the end, this album is nothing more and nothing less than one thirty-minute-long headbang.
