Asmodeus is an Austrian black metal band formed in Graz in 1996 by Tyr and Desdemon under the name Diabolus, before changing their name. The group initially combined black and death metal before moving toward a predominantly black metal style. They released their first proper demo, As the Winter Moon Bleeds, in 2000, followed by Embers of Aeon later that year. Their debut album, Phalanx Inferna, appeared in 2003, followed by Imperium Damnatum in 2006. Asmodeus toured and performed extensively across Europe, including shows with Belphegor, Dark Funeral, Naglfar, and Aura Noir. After a lengthy period devoted to songwriting, the band recorded its third studio album, ADAMANT, which was released in December 2018 by Talheim Records.
