Thrill Jockey spotify:track:0TBClFs57X7ZvTRrcGuTPm Aesthethica Liturgy was (afaik) one of the first bands to brazenly expand the borders of brutal black metal and doing so by making it an exercise in Swans-like texturing and mathematical hypnotizing riffing. It's a record that will disturb you, and won't let you relax, but it is a masterpiece for it.
