I'm still very into what I call late black metal, the introverted wandering stuff: Xasthur, Leviathan, Lurker of Chalice, WITTR. It's "late" in a sort of Harold Bloom-ish sense: belated with respect to the Scandinavian scene of the 90s, both paying tribute to it and completely defacing it at the same time.
The odd thing about Burzum is that it seems already "late" in this sense: there's as much of a gap between Burzum's Filosofem and Darkthrone's Transylvanian Hunger as there is between the latter and Xasthur's Nocturnal Poisoning. Varg Vikernes is some horrible kind of genius; one of the people interviewed in Soderlind and Moynihan's Lords of Chaos is a pastor who refers to Vikernes as "deep-souled", which is an surprising evaluation for a liberal man of the cloth to make of an extreme Aryan-supremacist, church-burning convicted murderer. But it's true: Burzum's music is seriously powerful, a disconcertingly authentic expression of earthly disgust and spiritual longing.
Also really loving Striborg at the moment:
