Review by Tomek on June 8, 2026.

How hard is it to make a sophomore album? Very hard, I would imagine. Repeat the debut, and you're accused of standing still. Change too much, and you risk alienating the very audience that got you there in the first place. The challenge becomes even greater when your debut is a masterpiece, as was the case with Kat's 1985 landmark "666".

Two years later, Kat answered that challenge with "Oddech Wymarłych Światów", an album many Polish metal fans regard as the band's definitive statement. While it isn't quite my personal favourite in their catalogue, denying its greatness would be an exercise in stubbornness. Across seven tracks and just under forty minutes, Kat delivered a record that refined everything they had established on their debut while pushing their songwriting and musicianship to a noticeably higher level.

What immediately stands out is the album's atmosphere. There is something distinctly musty and ominous about these songs, as though they emerged from some forgotten crypt. The band frequently launches into sudden bursts of speed that feel like shifting into fifth gear without warning, charging forward with youthful aggression and conviction. Yet Kat never relies solely on velocity. Acoustic passages, slower sections, and carefully arranged dynamic shifts break up the assault, preventing the album from becoming predictable. The contrasts feel natural rather than forced, giving the record a remarkable sense of flow.

Musically, this is unmistakably thrash metal, but a more mature and professional version of the style Kat presented on their debut. The production is significantly stronger, giving the riffs greater weight and definition. The guitars churn with a deeper bottom end, the solos from Piotr Luczyk are consistently memorable, and the rhythm section drives the material with confidence. Kat's greatest strength has always been their instinctive understanding of tempo, knowing exactly when to accelerate, when to pull back, and when to let a riff breathe. Like the finest records by Slayer, Sodom, Kreator, or Sepultura, every shift in momentum feels purposeful.

At the same time, the increased professionalism comes with a small trade-off. Some of the raw savagery that made "666" so dangerous has been softened. The songs remain dark and aggressive, but the primitive edge of the debut is less prominent. Whether that is a flaw or simply the inevitable result of artistic growth depends on the listener. For me, it occasionally feels like the band exchanged a little of their menace for greater precision.

Roman Kostrzewski remains the album's secret weapon. His vocals are clearer and more controlled than before, showcasing just how versatile he has become. Few vocalists could move so naturally between unhinged screams, rasping snarls, commanding shouts, and surprisingly effective clean passages. Even when the production smooths some of the rough edges, his performance remains captivating. His voice was one of the defining sounds of Polish metal, and "Oddech Wymarłych Światów" is among the strongest showcases of his abilities.

Of course, it helps that the songs themselves are exceptional. Classics such as 'Diabelski Dom Part II', 'Mag-Sex', and 'Głos z Ciemności' have long since earned their place in Polish metal history. More importantly, there are no weak links here. The album feels remarkably cohesive from beginning to end, each track contributing to a larger whole. Rather than a collection of individual highlights, it plays like a complete journey.

What makes "Oddech Wymarłych Światów" endure is that it successfully balances continuity and progression. The spirit of early Kat remains intact, but the songwriting is more sophisticated, the performances more confident, and the sound vastly improved. The band had clearly found its identity and was no longer searching for a direction.

This album doesn't really need a recommendation. It has long since secured its place as one of the cornerstones of Polish metal and remains a benchmark for thrash metal. A monumental achievement, a defining statement from a legendary band, and a record that continues to justify its reputation decades after its release.

Rating: 10 out of 10
