Black Metal Documentaries: Until The Light Takes Us
I've mentioned this documentary before, since I personally really enjoy it. This one exclusively focuses on the second wave of black metal that emerged from Norway, but I think it does a good job of exploring the thoughts and ideas that motivated several of the key figures in that movement. It looks at the music, but what it really examines are the social movement and the individual personalities involved. I personally find it fascinating, and I recently discovered that the whole thing is available in a single video on YouTube.
