Born of Osiris is an American progressive metal band formed in 2003 in the Chicago suburbs, when a group of teenage friends began experimenting with a mix of metalcore heaviness and deathcore aggression. In their early years they cycled through several names and stylistic directions, gradually shaping a musical identity built on technical guitar work, dense keyboard textures, and a futuristic, high-energy atmosphere. From the start, they aimed to combine crushing breakdowns with melodic detail and complex structures inspired by progressive metal.
Their early releases leaned heavily into deathcore, but the band soon expanded its sound with intricate arrangements and prominent synthesizer layers. This shift helped define them as one of the standout acts of modern American metal — a group that effortlessly blends brutality with ambience, precision with emotion, and raw power with cinematic depth. Throughout their catalog, the band explores themes of self-growth, metaphysics, transformation, and inner conflict, often presented through fast, interlocking riffs and spacious electronic elements.
Lineup changes have been frequent over the years, yet the core spirit of the band has remained intact. The current formation features vocalist Ronnie Canizaro, drummer Cameron Losch — the sole remaining founding member — and Nick Rossi, who handles guitar, bass, and keyboards. Together they carry the band’s signature sound into new eras, expanding it with modern production and increasingly complex musical structures.
Born of Osiris are also known for their intense live performances, where technical precision meets explosive stage energy. Over time they have earned a reputation as a band that constantly evolves, maintaining the backbone of metalcore intensity while enriching it with progressive ideas and atmospheric layers. Their blend of aggression, sophistication, and emotional depth has secured their place as a defining force in contemporary heavy music.
