Prior to the establishment of the band, the vocalist Christine Davis fronted the thrash metal band Buried Blood. Ryan and Oscar played guitar in two of Olympia's premier metal bands. After Ryan and Oscar's bands both broke up they decided to start writing and playing music together. The band's 2009 Christian Mistress demo, which cost only $500 to make,[3] and "Mother Of Mercy"/"The Hereafter" single gained attention from many notable heavy metal musicians, including Darkthrone member Fenriz.[1][4] As a result, the band signed to 20-Buck Spin Records and released their debut album, Agony & Opium in 2010.[1] The band released their follow-up album, Possession in 2012 via Relapse Records.[4][5]
On March 14, 2015, the band released a statement regarding American hip hop artist Kanye West's album art cover for So Help Me God (2015) and how they claim he copied their album art for Agony & Opium (2010).[7]
