Delia Derbyshire & Barry Bermange THE DREAMS is hellish and creepy. Recordings of people describing their dreams of claustrophobia and absolute terror. They often put emphasis on being followed by a dark image. The music consists of sustained chords for the background. They create an ambience which has similarities to Brian Eno ambient albums in the 70s and 80s except they were most likely taken from sound generators for THE DREAMS was created prior to the Moog Synthesizer became an item.
Delia Derbyshire was quite dark in the sense that she created darkscapes on several recordings which were luring and painted Visions of Hell beings. ELECTRIC STORM IN HELL from White Noise was quite disturbing.

Mort Garson BLACK MASS ...( Lucifer) was inventive music for the Moog Synthesizer. Not all of it aged well..but imo most of it did. Certain pieces are eerie no doubt..and some of the effects for voice on VOODOO were very unusual for 1971. The subject matter is quite disturbing and the music lures the listener in as a introduction to the occult. A occultism environment as such where in the 60s and 70s it began touching the surface through strange news reports of ritualistic killings and horror movies. I don't think of that when listening to Black Mass. I mainly hear dark themes with interesting improvisation. Mort Garson was a fine pianist and his improvisation on Moog Synthesizer is dimensional for 1971 and ahead of its time.

Wendy Carlos WINTER from Sonic Seasonings can be described as eerie. It's timeless!

Jeff Grienke- Timbral Planes is from the same swamp in Hell as WINTER and worthy of a listen.

Pauline Anna Strom...Spectre creates very dark imagery but mainly connects itself to the legend of vampires

Throbbing Gristle In The Shadow Of The Sun
This is basically noise. Abrupt sounding noise ...a guitar that sounds like a vacuum cleaner...but voices chanting or calling to the air and a direct replication of a cult from my hometown that worshipped at Menantico Ponds. People wearing black cloaks and masks. Chanting and pounding on drums. Programming rituals into tiny minds. People disappearing or murdered. People frightened by this cult...running through the Pine Barrens to get away and never knowing if they're running toward the cult or away from them...because of the improbable acoustics at Menantico Ponds putting even more fear in their minds...Of all people...Throbbing Gristle re-create this experience. It figures

Art Zoyd Nosferatu can sometimes sound too mechanical but it does contain some darkscapes that rare creations.

Peter Frohmader Cycle Of Eternity

Big, Beautiful, Dark & Scary by Bang On A Can All-Stars contains some very eerie pieces.

Daphne Oram- Oramics...eerie and disturbing not unlike some material by The Residents.

Stomu Yamashta Iroha- Ka....mostly dark sounding and some of the eeriest I've ever heard. Invokes images of shadows and phantoms...projects the feeling of communicating with the dead. Perhaps through a seance or an actual haunting.
