Heh, while I thought Blind Guardian was better known in the U.S.A., I'm definitely surprised to see Laibach mentioned in any country other than Slovenia and Germany. As for me, aside from stuff already mentioned:
Black (not what I listen to the most, but seems to be what you mentioned less): Burzum, Darkthrone, Isengard, Make a Change ... Kill Yourself.
Folk: Cruachan, Mägo de Oz (only one that doesn't have a lot of black in it), Rudra, Salem.
German Gothic: Das Ich, Lacrimosa.
Symphonic: Aesma Daeva, Diablo Swing Orchestra.
Industrial (i.e. if you like Laibach/Rammstein, check it out; it's more or less a fact that Laibach => Rammstein => Ruoska): Ruoska.
Self-important: Trivium.
Political (?): System of a Down/Serj Tankian.
Ministry, VNV Nation and Assemblage 23 are awesome.
