Genre: Darkwave/Gothic Rock

From what I can see, Sopor Aeternus (eternal sleep) is the brainchild of one person, singer and multi-instrumentalist Anna-Varney Cantodea, who seems to work with a variety of musicians on different albums. Their music is characterised as neoclassical, darkwave and gothic, and is rooted in Renaissance and baroque tropes. Anna-Varney themselves (the artist is gender neutral) appears to be an isolationist, never performing live, with much of their material instrumental, though they do sometimes venture off the dark, solitary path into the garish lights of popular/commercial music, always applying their own particular twist on any song, as below, with this weird cover of a Jim Steinman song.
and this even weirder, almost eight-minute version of Lionel Ritchie's "Hello"!
But yeah, much of their stuff is more like this:
