Have you ever found anything similar to DCD? You asked for recommendations like 'Spiritchaser' in my thread from almost a year ago, but DCD are rather unique among anything I've heard. There's ‘The Lotus Eaters’ tribute compilation, of course, but it's not quite the same as someone standing out by themselves.
Come to think of it, perhaps neoclassical darkwave is the closest thing out there: someone like Die Verbannten Kinder Evas (by a guy from Summoning), Stoa, Corvus Corax, Romowe Rikoito, In the Nursery, Sol Invictus, Ataraxia, Regard Extrême, etc. But this scene, together with neofolk and martial industrial, is a bit of a minefield in terms of nationalistic attitudes here and there.
Meanwhile, I think I never mentioned Camerata Mediolanense to you: e.g. ‘Salve, Mundi Domine, Caesar Noster, Ave’, ‘Quest'anima gentil’, ‘L'Homme Armé’. Camerata Sforzesca are very similar, but with emphasis on Renaissance music without the martial-industrial aspect.
