Nattefrost is the solo project of Roger Rasmussen, also known as simply 'Nattefrost,' best known for being the frontman of the Norwegian black metal band Carpathian Forest. The solo endeavor showcases his unfiltered vision of extreme music, embracing the raw and primitive aspects of the black metal genre. Rasmussen began Nattefrost in 2003 during a period when Carpathian Forest was on a break, allowing him to explore personal and often controversial themes in his music.

Nattefrost’s discography as a solo artist is a deep dive into the dark and aggressive recesses of black metal, with unapologetic lyrics and a grim aesthetic. Notable releases such as "Blood & Vomit" (2004), which was his debut solo album, establish the aggressive and grimy tone that would characterize his work. The controversially titled "Terrorist (Nekronaut Pt. I)" (2005) followed, further cementing his reputation for creating music that eschews convention and delves into themes of nihilism and misanthropy. His collaborative effort "Engangsgrill" in 2009 with Fenriz of Darkthrone fame is a testament to his standing in the Norwegian black metal scene, showcasing two influential figures in the genre coming together to create something that celebrated their roots. Nattefrost’s work continues to resonate with fans who appreciate the authenticity and rawness that he brings to the black metal genre.
