Oathbreaker, a Belgian metal band from Ghent, was formed in 2008. The group consists of guitarists Lennart Bossu and Gilles Demolder, drummer Wim Coppers, and vocalist Caro Tanghe. Oathbreaker emerged from the Belgian underground hardcore punk scene and integrated extreme metal and art music aesthetics. Their debut EP Oathbreaker was released in 2008. The band's first studio album, Mælstrøm, was released in 2011. Following this, they embarked on extensive tours across Europe and the United States. In 2013, Oathbreaker released their second album, Eros|Anteros. Their third album, Rheia, was released in 2016 and featured a more black metal, blackgaze, and post-metal direction. The band announced a hiatus in late 2017, playing their last show on December 20 of that year in Brussels. In October 2025, the band's reunion was announced for the April 2026 Roadburn Festival.
