DIETH formed in 2022 as an international project uniting three seasoned musicians: bassist and former Megadeth member David Ellefson, guitarist and vocalist Guilherme Miranda (ex-Entombed A.D.), and drummer Michał Łysejko (ex-Decapitated). Their style blends the musical heritage of death metal and thrash metal, combining technical and aggressive riffs, heavy groove sections, rapid-fire drumming, and raw guttural vocals — while also incorporating melodic and atmospheric elements.
In June 2023, DIETH released their debut album To Hell And Back through Napalm Records, marking their official entry onto the metal scene. The album delivers a fusion of thrash aggression and death-metal ferocity — from crushing tracks like “Wicked Disdain” and “The Mark of Cain,” to thrash-driven pieces and even emotional, slower passages. This makes DIETH far more than a simple “supergroup” — they are a strong and distinctive new force that blends the collective experience of its members into a fresh, modern form of death-thrash metal.
