I'll offer two reviews here, one very short and one not so short. First, the short one.
A brutal, searing portrait of a very human evil coupled with blisteringly nihilistic cosmic horror. I loved it, and if you love cosmic horror, black metal, or both, go read this. Now. 5 out of 5 stars.
And now, the longer review, but first let me reiterate that I am, in fact, a fan of black metal. I am listening to Aoratos's album "Gods Without Name" as I write this, for example.
When I first learned of black metal, I could not take it seriously (and often still don't, even as a converted die-hard fan, har har). Black metal was, and often still is, the music loved and listened to by angry, aggressive, often white, teenage boys with long greasy hair who hate their privileged lives and everyone in them. Often black metal is described by many amateur (and some professional) artists as the "most evil" of musical genres, which always struck me as more stage craft than genuine, dyed-in-the-wool ideology, a reason to dress in black and sing about Satan or other occult themes for the shock value. Perhaps I was (am?) mistaken in those observations, but perhaps not.
In CORPSEPAINT, black metal is more than a musical genre and its visual aesthetics; for the characters in this book, it's a religion, a way of life, an all-consuming nihilistic philosophy. As the synopsis on the back of the book says, "What they [the book's characters] discover...will go far deeper than the aesthetics of the genre, and the music they create -- antihuman, antilife -- ultimately becomes a weapon unto itself." This brutal, unforgiving novel invites the reader to not just stare but to fully descend into the abyss and to witness the horrible truth of Nietzsche's quote come to fruition.
What makes this novel so powerful and its horror so effective is that the characters, all of whom are abhorrent, loathsome people for one reason or another, are so well-realized and well-written that they felt real and therefore sympathetic. I cared deeply for them, in spite of who they are and in spite of myself, and I cared about what happened to them. Much like Jack Ketchum's devastating novel THE GIRL NEXT DOOR, this novel made me feel complicit in the characters' actions, and that, dear reader, I take as a sign of a masterpiece of horror fiction. Should you choose to read this novel, be forewarned: this novel is not for the faint of heart.
