The lineup centered on vocalist Tomas Lindberg, drummer Adrian Erlandsson, and guitarist Jonas Stålhammer, giving the project an immediate pedigree. Their debut Out of the Voiceless Grave (2017) and the Lovecraft-inspired Death, Madness, Horror, Decay (2021) were both released on Century Media to strong critical reception. The band disbanded in 2025 following Lindberg's death.
