Good black metal?
Well, I assume you know these bands, but if not the classics: Immortal, burzum, gorgoroth, darkthrone, and mayhem are all good for the basic groundwork of getting to know the genre (some bands you may also want to check out are bathory, celtic frost, and venom; they helped lay the way for black metal).
Here are some very rough generalizations of the type of black metals:
1. Raw black metal- Along the line of darkthrone, stuff like abruptum, tsjuder, koldbrann are good. These bands sometimes have low quality production are often very satanic. LLN bands are recommended further listening.
2. Symphonic black metal- Stuff such as early dimmu borgir, early cradle of filth (the most commercial examples, but y'know), bands like luna ad noctum, emperor, and anorexia nervosa.
3. Folk black metal- Black metal influenced by folk/folk metal. Personally my favourite, I recommend bands such as windir, falkenbach, isvind, kampfar, nastrandir, alkonost,
