Around the time when black metal was being birthed I grew bored with the sound and drifted into post-punk. I still don't listen to BM for pleasure, but I find the whole subculture fascinating, as I do with any group of ex-metal kids who warped into other things.
Without getting into the sticky realm of race theory, Lords of Chaos looked at a small part of the much larger black metal scene, a bunch of kids who were basically like well-off D&D geeks who took it too seriously. A lot of them are into Nordic nationalism, which in itself is not inherently racist, though there are certainly many who take it that far. I didn't do a BM newsletter, but I did a bunch of art for various zines and was deep into the tape trading scene back then (mid-late '80s), so got all the early records and demos. Sold 'em all off.
