Lords of Chaos (2018)
Dir. Jonas Åkerlund
As a long-time fan of early Norwegian Black Metal, I didn't know what to expect from LoC. Would it be parody, satire, mockery, or bullshit sensationalism? Wikipedia describes it as a 'horror-thriller film', which was worrying.
The answer, as I see it, is that the film is none of those things entirely, but it does lose its way as the narrative goes on. Before that, however, for about an hour of its runtime it's a pleasingly straightforward presentation with a comfortable amount of black humour and a half-decent (but mostly surface deep) depiction of the lifestyle that informed the music, and vice-versa.
It's based on the book Lords of Chaos: The Bloody Rise of the Satanic Metal Underground (1998) by Michael Moynihan and Didrik Søderlind. I've not read the text, but am familiar with how the stories were reported across Europe, firstly by having been a reader of the UK music presses at the time of the happenings — which might seem like too peripherally a connection, but is itself something that the film alludes to, in one of its most daft scenes — and later through personal research on the internet.
