I find London After Midnight and the Scary Bitches to have similar over the top vibes.
Vampyre Erotica by Inkubus Sukkubus also comes to mind.
Maybe Tragic Black and Rosetta Stone as well?
Tell me what you think, Fear Cult is hard to pin down.
Also it doesn't realy sound like it and you probably know it but I always feel like Church of No Return by Christian Death goes with Fear Cult.
