Sidian returns with force on their new single, “Elegiac, Absent Catharsis."

Sidian returns with force on their new single, “Elegiac, Absent Catharsis,” heralding the long-awaited arrival of the band’s debut full-length—set for a Limited Edition CD release on December 26, 2025 via Rebel Pyro Musick. Blending a haunting atmosphere with razor-edged technical precision, the track captures the band’s evolution from their early demo days through their post-hiatus resurgence.

Fans may recall Sidian’s 2019 EP Carry My Bones and their pre-2012 demo cycle (“Yersinia Pestis,” “Tombs,” “Anamorphosis,” and “Where the Sun is Silent”), which first hinted at the band’s unique melodic extremity. Their 2012 studio return—“Eternal Bloom of Lamenting Dawn”—recorded with producer Zack Ohren (Castle Ultimate Studios) and featuring drummer Alex Bent (Trivium/Testament/Arkaik), marked a pivotal leap in songwriting ambition.

“Elegiac, Absent Catharsis” continues that progression—somber, searing, and cinematic—offering a powerful first glimpse into Sidian’s fully realized sound.
