I was going through Youtube looking up the trailers for the "Scream For Me Sarajevo" documentary about Bruce D.'s trip and show in a war zone from 1993 when I saw on the far right an 'up next' video for another war time doc regarding metal.
This one is "Syrian Metal Is War" and is very well done. Mostly sub titled from Arabic, the documentary follows bands, scenes, recordings, and shows of various Syrian and Lebanese groups and the fans. Closing in on 90 minutes, it is both scary and inspiring to see bands and fans going to shows in wartime and also facing jail time for being satanists. A unique look at global metal for sure.
I would imbed the video here, but I doubt anyone would watch it from here as it is 90 minutes; so check it out here: https://www.youtube.com/watch?v=ZP_HV-R-KGg&t=2748s
