Rasmussen was born in
Sandnes,
Rogaland County, Norway. His first musical ventures were with the black metal band The Childmolesters, which he founded in 1990 alongside his future Carpathian Forest bandmate Johnny "Nordavind" Krøvel. The band was very short-lived, ending in the same year; from its demise arose Enthrone, which changed its name to Carpathian Forest in 1992. During Carpathian Forest's first years of existence, Nattefrost used the pseudonym
Lord Nosferatu; he would not be known as "Nattefrost" (
Norwegian for "Night frost") until 1995, when the band released its first
EP,
Through Chasm, Caves and Titan Woods. In 2000 Nattefrost formed his first side project, World Destroyer, alongside Eivind Kulde and his Carpathian Forest bandmate
Daniel Vrangsinn. The band released a
demo album,
Diabolical Quest, in 2004; it is their only release so far. He would form the duo Kreft in 2011 alongside Patolog Falk, releasing in the same year the EP
Lommemannen. In 2003 Nattefrost announced that he would begin a solo project, and in the following year he released his first album,
Blood & Vomit. His second album,
Terrorist (Nekronaut, Part I), came out in the following year and counted with guest appearances by numerous musicians, such as
Carl-Michael Eide, Sanrabb of
Gehenna and
Hoest of
Taake. He also released a live EP in 2006, entitled
Drunk and Pisseskev at Ringnes 2004, which was recorded during his first show, in Ringnes, and a compilation of rarities,
Hell Noise and Live Terrorism, came out in 2008. Nattefrost's latest release was the 2009
split album Engangsgrill, with
Darkthrone's
Fenriz's
doom metal side project Fenriz's Red Planet. In 2016 he collaborated with
Urgehal, providing vocals and lyrics for the song "Endetid", off their seventh album
Aeons in Sodom. He previously collaborated with
Green Carnation (on
Light of Day, Day of Darkness), Taake (on
Hordalands doedskvad) and
Aura Noir (on
The Merciless). ==Discography==
