The Permian-Triassic boundary is a great mystery of geological science: an event in which over 83 percent of all genera died. This period separates the Paleozoic Era from the Mesozoic Era – two of the great eras in our planet’s history. If you were a 6-year-old obsessed with dinosaurs like I was (or a 29-year-old like me now for whom that obsession still lives!), you might recall that the Mesozoic Era was when dinosaurs ruled the Earth. So what better two bands to explore this event than Thecodontion and Vessel of Iniquity? Thecodontion brings two black-and-death metal tracks from the Supercontinent recording sessions, which was my #4 album of 2020. These explore two taxa that emerged after the extinction, heralding the start of the Age of Reptiles, using dead-serious and extraordinarily researched history of both species’ classification schemes. Both tracks feature the band’s characteristic drum-and-bass approach to death metal with octave pedals to produce a unique, clean “lead guitar” tone. They’re riffy, clean, and filled with evocative solos that will click for fans of last year’s LP. And yet for this life to have flourished, death first occurred – that’s where Vessel of Iniquity comes in. “The Great Dying” is another name for the extinction event, and Vessel of Iniquity’s mixture of black metal and noise is perfectly suited for the harrowing, slow death brought to tens of millions of species. The track’s eleven minutes begin with a roaring wall-of-noise that gradually settles into a slow dread, later culminating in SP White’s layered shrieks and mournful guitar strums. Two stories of the same history – one of life, one of death – and an excellent split for all fans of extreme metal.
