Nightmare Fuel: Coil
"Queens Of The Circulating Library", a nearly fifty-minute track mostly composed of resonant drones, goes into this territory about halfway through, with a spoken-word piece that ends up invoking Nothing Is Scarier.
Their side-project Zos Kia has the song "Rape", inspired by personal experience, specifically that of their vocalist. It becomes very intense very quickly.
"Poisons" isn't any easier to listen to either.
In a similar vein, "The Tenderness Of Wolves", if only due to the looping infant screams.
"Blood From The Air", especially the sudden rush of strange, high-pitched noises halfway through. That, and the lyrics, which pretty much about detailed Scenery Gorn.
The Music To Play In The Dark duology, which manages to keep up a consistently unsettling atmosphere throughout.
"It's In My Blood," primarily due to its shrieked, blabbering vocals and the dramatic orchestra playing in- and out-of-time with the beat.
"Things Happen." First we have Jhonn's distorted shouting, then Annie Anxiety's sultry-voiced spoken word, loaded with creepy innuendo and implication, all to a rather tense melody.
