Amidst their constant musical evolution, this album stands as a bold departure, embracing the ferocity of heavy metal to mirror the chaos of our times.

Infest the Rats’ Nest Album Overview

Track Analysis

The album’s power-trio formation showcases Stu Mackenzie on vocals and guitar, accompanied by guitarist Joey Walker and drummer Michael Cavanagh. The immediacy of their sound channels thrash metal’s roots rather than its complex intricacies. Tracks like “Planet B” resonate with Deep Purple’s fervor, while “Mars for the Rich” evokes the iconic groove of Black Sabbath. Amidst the metallic onslaught, hints of King Gizzard’s stoner-rock influence emerge, particularly in the weighty “Superbug.”

Production and Instrumentation:

The production on “Infest the Rats’ Nest” is raw and unfiltered, embracing the unrefined spirit of thrash metal’s origins. The gritty guitars and thunderous drums blend seamlessly, creating an intense atmosphere that mirrors the album’s themes. The absence of polished perfection enhances the album’s primal energy and emotional resonance.

Songwriting and Lyrics

Lyrically, the album delves into doomsday prophecies, ecological disasters, and a vehement disdain for those perpetuating harm. The minimalist rhymes and urgent howls enhance the apocalyptic mood, channeling the collective sense of impending catastrophe. While the narrative on the second side touches upon escaping to Venus, the album largely remains thematically focused on its grim outlook.

Vocal Performance

Stu Mackenzie’s vocal transformation into a venomous growl adds a layer of ferocity to the album. Abandoning his natural singing voice, he adopts a hook-free, aggressive delivery that aligns with the album’s doomsday ethos. The harsh vocal style becomes a driving force, infusing the tracks with a sense of urgency and desperation.

Comparisons and Influences

“Infest the Rats’ Nest” skillfully bridges thrash metal with ’70s-metal influences.

The fusion of these elements creates a unique listening experience that pays homage to metal’s history while embracing modernity.
