What a fucking amazing performance!! Black Metal rarely works well live, in my opinion.
It's the kind of music that's better enjoyed on your own and maybe while lying down in your bed and with lights off, it's the perfect soundtrack to dark solitary moments and not any kind of social situation.
This is one of the reasons some of the Best Black metal bands never perform live, with some of them being one man "bands" where the same artist lays all the instruments and does the vocals too.
But somehow these guys make it work very well live, the performance is technically perfect and the sound and emotion don't lose their potency and intensity. Fucking unreal, I really hope I get to see these guys live some day.
