I'm curious about this as well, but I actually prefer any recs to be doom metal. I've actually got a couple recs myself, but they are doom metal, so sorry about that.
Black Hole is an Italian doom metal band that put out their first album, called Land of Mystery, in 1985. This is really creepy tinged doom, with lots of touches of church organ, and vocals that sound very ghost-like. Their second album, Living Mask, was recorded between 1988 - 1989 but not released until 2000. The second album is quite good but has a HUMUNGOUS flaw--the poorly programmed drums. You have to hear it to believe it. The first time I listened to the album I couldn't stop laughing because of the drum programming. But after a few listens, and after the shock wore off, I began to get used to it, and now I think the drum programming actually fits the music quite well and is part of the album's charm. But make no mistake, I always loved everything else about the album, even on first listen. Black Hole actually finally put out another album like less than two months ago, called Evil in the Dark. I haven't heard any of it yet, but I am eagerly waiting for my copy to arrive in the mail.
Black Hole - Demoniac City. From their first album, Land of Mystery. This is a weird song for them because the intro embodies everything the band is about, but after the intro, it's by far the least doomy thing they ever put on an album. But maybe you'll like that because of it.
Black Hole - Living Masks. From their second album, Living Mask. This song doesn't really have organ, but the synths it does have are equally chilling. Beware the drum programming!
Antonius Rex is not on the archives, as they are known as an Italian prog rock band from the 70s. Starting at their 1980 album Praeternatural, they started adding doom metalish guitar riffs to their music, but not enough to have them qualify as actual metal albums. IMO, except one: Neque Semper Arcum Tendit Rex. There is an interesting story behind this one. The band alleges they recorded it as a demo in 1974 and was going to release it on a label, but the label didn't like one of the tracks, so it got shelved, and it was finally released to the public in 2000. This 2000 release is pretty much a doom metal album. But other than doom metal, there are church organs all over the fucking place. The vocals are this creepy spoken word recitations, I'm assuming in Italian. What's insteresting is that, some people claim that Antonius Rex's claim this was recorded in 1974 is not entirely true. That most of it was probably recorded back then, but the heavy guitars were all added much later for the 2000 release. Someone on MA I was briefly discussing this with said one piece of proof is that the technology to get such high gain distortion on a guitar was not available in 1974, and that assertion seems accurate to me. But "fake" or not, I love the damn thing, and I think anyone seeking for Abysmal Grief-like music would do well to check it out.
Antonius Rex - Neque Semper Arcum. From their 2000 album, Neque Semper Arcum Tendit Rex. The metal comes in about halfway through the song. This album contains very minimalist drumming throughout.
