Xasthur pioneered the hipster invasion, because they made more linear versions of ambient black metal "Linear" is a terrible choice of word to describe the music of Xasthur, which is far more concerned with "vertical" depth
Maybe. I was thinking less of the actual melodies and phrase patterns, but something more simple in the matter of overall sound and presentation. Linear means that "what you see is what you get" and it goes through the motions, no part of the package/product being at odds with any other part. There is only one constant mood, which is very unnatural. But hipsters latched on to the idea that raw black metal can be approached as soundscape music, as blissful static drones and anti-structural modern art, particularly when musicians such as Thurston Moore of Sonic Youth and Stephen O'Malley of SUNN O))) quoted black metal as an inspiration. We are talking about an audience that would not be very much interested in Burzum's methods of conjoining Destruction riffs with Schulze's kosmische rock, Demilich's obtuse fusion or Immortal's polyrhythmic Morbid-Angel-clashes-with-Imperial-March-theme holocaust metal, not to mention more traditional forms of metal. Indie/weird music fans are often not fans of music
at all, the opposite in fact.
Xasthur built all of his work from a passage to similar, monotonous walls of hypnotizing buzz that indeed, are able to conjure reflective depth on occasion through the careful buildups of essentially simple melodies first at odds with each other but eventually resulting in some kind of a cathartic cacophony. Xasthur did
perfect this technique. But it was especially perfect for the minds of the fans of noise, freakout and "obscure shit". Also, because Xasthur's concept was tame and apolitical, it was less problematic to approach it than, say, Les Legions Noires or Blazebirth Hall black metal which otherwise would prove themselves far more "blissful". Xasthur (as Leviathan and Deathspell Omega) probably had good intentions but as fate would have it, they became the poster boys of the "new school".
