Nostalgia might play a part in this as it was the first death metal album I bought. However, I think everything about it screams timeless classic. From Vincent's ghastly incantations to Trey's twisted and demented riffing and Pete Sandoval's punishing blasts which are some of the most tasteful I've heard to this day. It also has an ancient aesthetic to it that I really love and a very fitting production job. Then there's the songs themselves which are all fantastic, full of devastating rhythms and flesh cutting melodic riffs - when I consider "Blasphemy" to be the worst track then you know you've got a good thing.
It's also insanely fucking memorable. Lines such as:
"Souls are being raped by the maze, lost in these halls endlessly!"
"Ride the wings of death!"
"Ia iak sakkakh iak sakkakth, Ia shaxul, Ia kingu ia cthulu ia azbul, Ia azabua"
"Dead your God is dead, fools your God is dead, useless prayers of lies behold Satan's rise"
"God of lies and greed, God of hypocrisy we laugh at your bastard child, no God shall come before me!"
Are forever burned into my memory. They're also delivered with such conviction and venom that even if they sound childish out of context, they come across as sincere and like they really believed in what they were singing.
The only criticism I can come up with for the album is that it feels like a bit of a collection of songs (albeit really fucking good songs) rather than a cohesive album. Which is why I favour Blessed are the Sick. If I'm looking for an all out assault on the sense I'll reach for Altars, though.
"Immortal Rites", "Maze of Torment", "Lord of All Fevers and Plague" and "Chapel of Ghouls" are easily some of the best death metal tracks ever. And the rest are almost as good.
