Wow thats great Emperor are uniting for Wacken cuz i'm gonna be there next year for wacken!
About black metal..........
I nowadays listen to more BM from the U.S. bands like Judas Iscariot, Kult ov Azazel, Ibex Throne, Krieg, typhus, fog, black witchery, Xasthur, revenge, Noctuary, Demoncy, Inquisition, Thy Infernal , ect... I don't think there has ever been a BM band from the U.S. thats ever gotten really big.
Also listen to a bunch of NON commercial underground BM (the kind of bands you won't see as popular as Cradle or Dimmu) Bands like Falkenbach, Dark Fortress, Weltmacht, Vordven, Wigrid, Kvist, Craft, Impaled Nazarene, Blasphemy, beherit, Diaboli, Algaion, Woodtemple, Nytalgia, Nokturnal Mortem, Nargaroth, ect.....ect......
Of course I still listen to bands from the older Norwegian BM scene like Emperor, Satyricon, Gorgorth, Aura Noir, Burzum, Dark Throne, Mayhem., Enslaved, Immortal, ect...ect......
Nowadays though the Norwegian BM scene has become nothing but mostly a memory. Don't get me wrong there are still some bands there putting out good music but overall Norse BM isn't quite what it use to be.
Nowadays
