IATT (pronounced “eye-at”) is a boundary-pushing progressive extreme metal band originally formed in the Philadelphia area. Emerging in 2008 under the name I Am The Trireme, the group evolved both sonically and stylistically into what is now known simply as IATT—a project defined by ambition, atmosphere, and genre-defying composition.

Blending elements of progressive black metal, death metal, and cinematic orchestration, IATT crafts immersive soundscapes that balance brutality with melody and experimentation. Their music draws from a wide range of influences—from classical composition to technical metal—resulting in a dynamic and often unpredictable listening experience.

The band has earned recognition in the underground metal world for releases like Nomenclature and Magnum Opus, showcasing a sound that fuses dissonant aggression with soaring, atmospheric passages and intricate musicianship. With a reputation for pushing creative boundaries and refusing to be confined by genre, IATT continues to establish themselves as a forward-thinking force in modern extreme metal.
