No, you're just a fucking moron. Genevieve, their most popular and well-renowned album, is completely original work by them. Two of their subsequent recordings were stolen, a lot of their previous demos were faked. There's a biiiig fucking difference.

Indeed. Surprisingly, a lot of those sort of bands utilize strikingly complex (melodically speaking) tremolo-style riffs that sometimes might not seem out of place in BM, and since shoegaze is semi-related, the black metal scene really IS starting to embrace that.
 
Is Kult Ov Azael - The World, The Flesh & The Devil worth $6? I've heard a few samples but wanted to see what someone thinks whom owns the album.
