One of these men (Vikernes) was in prison at the time of filming and one concealed his face and voice for some reason or another. The documentary's title is the English translation of the Burzum album Hvis lyset tar oss a critical and influential album in black metal circles.
The documentary was very informative, in a way. Not too much information about the formation of black metal was there, but the psyche and ideas that resulted in it are very apparent. What really amazes a lot of people is the personal side of these musicians- behind the corpse paint and growling and fuzzy riffs are some highly intelligent, non threatening people with a good sense of humor and a very appealing demeanor.
Then again there was a point when Fenriz tore an interviewer a new asshole.
I wish I was in a trailer camp listening to Anthrax.
So, if you like documentaries or black metal check this out- it's streaming on Netflix.
