"People who aren't familiar with Petbrick, the genre-bending 2-piece of Wayne Adams and Iggor Cavalera, might not know what to expect seeing those two names together. One known for their iconic extreme metal performances and the other for their heavy electronic focus, the two things at first glance might not seem to compute.

Their 2nd LP feels like it couldn't be named any more aptly; occupying the space between where two worlds converge, Petbrick are smack bang in the middle of the process of bringing us something huge and heavy alike, with plenty borrowed from both sides of the coin. It's handy, then, that opening track "Primer" is also named perfectly; the tempo-building electronica blasted in half by a sonic barrage of high-intensity drum and bass that gives us a brain-mashing taste of what this album is about.

"Arboria" keeps it going, testing the walls with hammering blows as Iggor slams away in an unmistakable Sepultura style. The pendulum swings in "Pigeon Kick", an unadulterated bit of old-school drum and bass before "Raijin" delivers a drawn-out, spooky synth-fest that is very pleasing on the ear but maybe not quite in the right spot, dropping the pace following such a high-energy track.

Liminal is heavy on collaboration from artists of a range of genres. Our first lyrical intervention proper comes courtesy of doom rappers Lord Goat and Truck Jewelz, who add stuttering bars to the pounding bass of "Lysergic Aura" to great effect. "Dambella" floats through an eerily beautiful soundscape before dropping an anvil on you, while "Ayan" is another purist effort that ramps off the end of it beautifully, carrying on that building flow." - Metal Injection
