Diamanda Galas's *Plague Mass* is a live vortex of grief, rage, and liturgical vocal sorcery. Recorded in a cathedral during the height of the AIDS crisis, it uses nothing but her four-octave voice and tape loops to create a sonic monument to the dead. Unforgiving, unmissable, and unlike anything else.
The first time I heard Plague Mass, I had to stop what I was doing and sit down. That doesn’t happen often. But this wasn’t music as I knew it — it was something closer to an exorcism.
Recorded live at the Cathedral of St. John the Divine in New York in 1990, the album captures a woman standing alone under a cavernous stone ceiling. No band. No backing tracks beyond her own layered tape loops. Just Diamanda Galás and a microphone, turning her voice into a weapon against the political and social silence that surrounded the AIDS epidemic.
She had already lost her brother to the disease. The album is dedicated to him, and to everyone else the government had decided was expendable. That context isn’t background — it’s the entire reason this thing exists.
The Instrument
Galás is often described as a vocalist, but that undersells it. She treats her voice as a physical, almost mechanical instrument capable of microtonal howls, multiphonic drones, and a controlled scream that seems to bypass the lungs entirely.
She studied for years under classical training, then abandoned it for something more useful. On this album, you hear Byzantine chant rub against blues moans and free jazz vowel explosions. The transitions aren’t smooth — they’re jarring, because that’s the point.
There are no safety nets here. No reverb to hide behind. The Cathedral’s natural acoustics provide all the resonance you need, and her voice fills the space like a fire alarm.
The Setup
Technically, the album is bare bones. Galás worked with a small crew — she handled the tape loops herself, triggering them in real time. The engineer (credited as John Kilgore on the original sessions) captured her voice with minimal processing. What you hear is what happened that night.
The album’s centerpiece, “This Is the Law of the Plague,” unfolds slowly, a litany of names and accusations. She doesn’t so much sing as inhabit the words. By the time she reaches “You must be certain of the devil,” you understand she’s not performing a role. She’s speaking from experience.
I’ve seen people walk out of her shows. I’ve also seen people weep. Plague Mass is not background music. It demands a kind of attention most of us aren’t prepared to give.
But if you sit with it — really sit, no phone, no distractions — it becomes something else. Not entertainment. Not even art, exactly. A testimony.
And that’s why it still matters thirty years later. The plague isn’t over. Neither is the rage.
