Mystruin unleashes pure black metal savagery. The riffs sound like a buzzsaw revving in the red zone, or a swarm of titanic hornets. The drumming is furious — and technically very impressive. The vocals are frighteningly venomous. But the music isn’t a non-stop storm. Before the song ends, it drops down into a few doom-drenched dirges. The music has a very heavy low end, which enhances the apocalyptic quality of the melody. Ravaging stuff, and very well-executed.
