Metalfag here,

Slayer used to be one of my favorite bands growing up and was until Q posted Slayer lyrics and everything started making sense. The symbolism was always there not only with them but almost all metal back then was satanic-themed. i always thought they were fucking around, or wanted to be edgy&shocking but damn was I wrong. Hopefully they weren't doing any black mass en masse curses on us from listening to their music(they were).

Anyways. Heres the video of seasons in the abyss by Slayer. Within the first ten seconds are the Pyramids, the Sphinx and pentagrams.
