The history, occult and horror themes of metal have become something of a cheesy cliche.
But they are awesome when done right and Secret Treaties has to be one of the genre's most influential albums in that area.
The twisted lyrics are some of the best the genre has ever produced.
They show don't tell and they're poetic, smart and about as creepy as it gets.
ME262 features WW2 from the Nazi perspective.
The dirty forbidden sex of Dominance.
The horror movie/sci-fi plots of Cagey Cretins (mindless killer), Subhuman (drowning and rebirth), Harvester of Eyes (metaphor or literal?) and Flaming Telepaths (mind control).
And then there are the elements best represented by Astronomy that were supposed to be part of the Imaginos saga — a paranoid concept album about history and alien world domination — that failed to fully form here and were revisited in the 1987 album of the same name.
It's the sorta stuff that a fan of horror and sci-fi should find irresistible.
And it definitely helped form a major element of the metal that was to come.
*****
For the record, virtually every song on this album sounds better (heavier) live.
