Oathbreaker is a post-black metal band from Gent, Oost-Vlaanderen, Belgium. Formed in 2008 and currently signed to Deathwish Inc. They started life as a hardcore band with metalcore elements (debut EP and Mælstrøm), their musical style has increasingly incorporated elements of black metal whilst retaining their hardcore framework (Eros|Anteros) and more recently, forgoing their hardcore tendencies and fully embracing a post-black metal sound (Rheia) with even some shoegazing and folk sensibilities as well as considerable post-metallism.
