FOR THOSE ABOUT TO ROCK, WE EXCOMMUNICATE YOU

So get this. The year is 12-something-or-other, let’s say 1288 because numbers are for nerds, and deep in the clammy asshole of Westphalia, the nuns of Saint Mechtild’s-in-the-Mire are bored. Like, existentially, soul-crushingly bored. Their days are a relentless cycle of prayer, weaving suspiciously scratchy habits, and trying to pretend Brother Gerald from the local monastery doesn’t smell like he’s fermenting his own feet. The highlight of their week is when the lepers come to the gate, and that’s mostly just for the gossip.

Enter Sister Katherina. This was a woman who, according to the probably-fake *Chronicles of Brother Eustace*, once tamed a wolf by shouting at it in Latin and had, on no less than three occasions, tried to "improve" the communion wine with fermented berries. One Tuesday, while stuck on bell duty, a divine—or possibly demonic—thought struck her. The big bells were for BONG... BONG... BONG. But the little sanctus bells? They went *ding-a-ling-a-ling*. And the psaltery—that dinky little harp thing they used to accompany their dreary chants? What if, Katherina whispered to her confidant, the perpetually horny Sister Agnes, what if you hit it? Like, *really* hit it. With a goddamn spoon.

Within a fortnight, they had a band. Katherina on the main bourdon bell, laying down a bass line that could loosen fillings in the next village. Agnes, wielding two soup ladles, thrashed the psaltery into submission, producing a sound somewhere between a hornet’s nest and a cast-iron skillet to the face. Two other nuns, Sisters Joan and Cunigunda, provided the vocals—scrapping the melodic psalms in favor of a guttural, rhythmic shouting of the Penitential Psalms. They called it "Hymnus Malleus." The Hammer Hymn. It was loud, it was angry, and it was mostly about how much God was going to fuck up their enemies. The local peasantry, used to the gentle wafting of Gregorian chants, heard this unholy racket and assumed the Apocalypse had finally arrived. And in a way, it had.

The sound spread faster than syphilis in a sailor town. Convents from Flanders to Bavaria started their own "Hammer Hymn" choirs, each trying to out-shout the other in devotional fury. Pilgrims’ ballads were rewritten with driving, bell-heavy backbeats. The new music, which one horrified chronicler dubbed "Clangores Diaboli"—the Devil’s Clang—was a sensation. Of course, the party couldn’t last. The local bishop, a doughy, sweating heap of ambition named Adalbert, heard the racket during a particularly nasty hangover and nearly shat his vestments. This wasn’t music; it was a goddamn riot with a holy water sprinkler.

Adalbert sent a screaming missive to Rome, and the Pope—I dunno, Innocent the Whateverth—issued a bull declaring the Devil’s Clang to be "an offense to the ears of God and a direct invitation for Satan to enter one’s lady-regions." The Inquisition got involved, which is never a good sign. Sister Katherina was hauled before a tribunal, where she allegedly defended herself by claiming the Archangel Gabriel had appeared to her in a dream and told her that "Heaven slaps, yea, unto the firmament." They didn’t buy it. The psalteries were burned, the bells were re-consecrated, and the nuns were put on a permanent diet of bread, water, and soul-crushing silence. And so, the first age of metal was over before it even bought its first leather codpiece.
