Michigan’s Kaptain Kollnot returns with a fourth independent release The Aquarius Shift, an ambitious 4 track EP that clocks in at 25 minutes. While the band hasn’t yet found its definitive voice, this progressive thrash metal project showcases their continued growth and effort. With standout guitar work and a strong spirit, there’s plenty here to appreciate, even if not every moment hits with the same force. The EP opens with The Soul Plan (7:00). It has a grand fast paced opening with a melodic power metal edge. It is energetic, cleanly executed, and full of momentum. Once the vocals enter, there’s a shift toward a more old-school metal vibe. While this section leans a bit on familiar territory stylistically, fans of classic heavy metal will likely enjoy its nostalgic flavour. A well placed lead break just after the halfway point adds some flair and contrast, making this track a strong opener overall.

Mankinds (5:08) launches straight into a thrashier tempo, with sharp, fast riffing. This is accompanied by vocals from the start. Whilst the lyrics could benefit from more depth and cohesion the raw energy carries much of the track forward. There are effective tempo changes that keep things moving, and some gutsy, satisfying riffs underpin the whole thing. The lead guitar break is clean, expressive, and well situated in the song. While the vocal performance might not be for everyone, the instrumental work shines, especially for fans who appreciate tight, riff driven metal. Third up is A New World (4:28), which starts with a dissonant lead guitar intro before launching into a tight, fast paced rhythm. The melody is catchy and well structured, supported by solid rhythm work that keeps it grounded. The riffs are particularly memorable, simple, but effective, and they bring a welcome hook that gives this track some replay value. A very enjoyable track.

The closer, The Nature of Evil (8:26), is the most dynamic and emotionally varied track on the EP. It begins with a mellow, melodic intro that gradually unfolds into something darker and more intense. The vocal performance steps up here incorporating both a guttural raspyness and screams. At times there are small glimpses of James Hetfield, particularly in the grittier moments. The pacing slows considerably midway through, allowing for a melancholic lead guitar break that adds real atmosphere. The riffs return with weight before the song winds down and fades out, giving the EP a thoughtful, slightly brooding, conclusion. Across the EP, the vocals can feel slightly overstretched in places, and the lyrics could be more developed, but the musicianship especially in the rhythm and lead guitars is strong. There are some genuinely enjoyable moments scattered throughout, and while the overall sound occasionally lacks originality, the heart behind the project is unmistakable.

This is an earnest and well-crafted release from a project still shaping its identity, and fans of old school leaning metal will likely find more than a few reasons to keep listening.
