Antestor is a pioneering band within the Christian extreme metal genre, hailing from Norway and known for their unorthodox integration of black metal musical styles with a message of Christian faith. Formed in 1990, the band’s moniker means 'testify' or 'call to witness' in Latin, reflecting their desire to use their music as a testimony of their beliefs. Despite their controversial stance within the metal community that generally encompasses darker themes, Antestor has steadfastly produced music that challenges the boundaries of black metal ideology with their overtly Christian lyrics and ethos.

Over the years, Antestor has seen various lineup changes and has faced significant opposition in the black metal scene, yet they have earned respect for their musicianship and the authenticity of their work. "Martyrium," their unofficial first album released in 1994, is a seminal work that exhibited raw production and somber themes within a death/doom metal framework. Their next milestone release, "The Return of the Black Death" (1998), saw them fully embracing black metal soundscapes while delivering an unapologetically Christian message. "The Forsaken" (2005), one of their most critically acclaimed works, further cemented their status in metallic echelons with its well-crafted melodic black metal style. Their most recent album, "Omen" (2012), continues their legacy, showcasing the band's evolution both in lyrical depth and musical complexity. Despite a sparse discography, Antestor is admired for their contributions to the Christian metal scene and their role as one of the progenitors of Christian black metal.
