Not a documentary (as you'd rightfully and logically expect from the packaging), but a (likely bootleg) combination of scattershot VHS clips, with only tenuous connections to one another.
This shady set begins with three low-quality VHS transfers of live songs by Mayhem, Venom, and Celtic Frost (some with digital noise/tape glitches intact). Then we get a brief clip called "Consejo Black Metal", which amounts to a Spanish or Mexican guy in corpse paint ranting. There are some priceless (and hopefully tongue-in-cheek) shots of him reading Bram Stoker's "Dracula" in an outhouse. I couldn't figure this out. Finally there are two "photo galleries", one called "Black Metal Girls", and a "Norwegian Black Metal Photo Documentary", both of which contain some curious still images, but they are all unlabeled and unorganized, so who knows what bands are here? No documentation, just raw materials easily accessed online, I'm sure.
If that weren't enough, the whole deal runs in 20 minutes! Very, very shameful. This is a simple case of a company preying upon a faithful fan base, and releasing shoddy product. If that's not pure evil, I don't know what is.
