With every generation comes a great war. It may take years to fully reveal itself, but the seasoned warrior knows preparation is everything. Now in 2025, Bay Area thrash metal icons TESTAMENT return with their fourteenth studio album, Para Bellum, via Nuclear Blast Records. Taken from the Latin phrase Si vis pacem, para bellum—“If you want peace, prepare for war”—the album stands as both a battle cry and an observation of humanity’s uneasy alliance with its own creations. As technology accelerates and disconnection grows, Para Bellum sees TESTAMENT reflecting the modern chaos through music that’s urgent, sharp, and unflinchingly human.

True to their legacy, Para Bellum is a masterclass in dynamic thrash songwriting, guided by founding guitarist Eric Peterson and vocalist Chuck Billy, who continue to lead the band with vision and force. Each track on the album stands on its own—distinct in structure, key, and atmosphere—but when taken together, they create a record that flows seamlessly, puzzle-like, through eras and styles.

To the delight of many life-long Testament fans, this record also sees the inclusion of a ballad for the first time in many years. Precisely formulated to weave effortlessly with the album, “Meant To Be” contains a world of variety within itself. This also marks another novel moment for the band using true, orchestrated strings performed by world renowned cellist Dave Eggar.

Recorded with Juan Urteaga and mixed for the first time by Jens Bogren, Para Bellum is extremely polished and operating at full throttle. In its opening notes, Para Bellum nods to the past by resurrecting a lost bridge from The Legacy—a full-circle moment that anchors the album’s expansive sonic journey. And as it ends, it does so peacefully, with a moment of classical-esque finger picking long used by Peterson to warm up his hands before battle. From first note to last breath, Para Bellum is an album by warriors—crafted in chaos, and built to outlast the wars to come!
