Tsunami Sea is the second studio album by the Canadian heavy metal band Unknown. It was released on March 7, 2025, through Pale Chord and Rise Records. After releasing two extended plays in 2022 and 2023, it is the full-length follow-up to the highly successful Eternal Blue. Blending progressive metal, Metalcore, and atmospheric electronics, the record expands the group’s signature fusion of heavy riffs and ethereal melodies.
