Shagrath is the vocalist of the famous symphonic black metal, Dimmu Borgir.
Stian Thoresen (alias Shagrath) was born on November 18, 1976 in Jessheim, outside of Oslo, Norway.
Shagrath is one of the founding members of Dimmu Borgir, along with Silenoz and Tjodalv. Shagrath's change from playing guitar to vocals is a part of what changed the band's sound. His contributions extend into the use of keyboards, bass guitar, and drums; as can be heard on For All Tid. Since the departure of Mustis in 2009, Shagrath has returned to the keyboards.
Shagrath also played guitar and drums in Fimbulwinter until the band split up in 1994. Fimbulwinter released one album, Servants of Sorcery, through Hot Records in the year of 1994. Shagrath also played keyboards in another Norwegian black metal band called Ragnarok. Another unknown band was Starkness, a solo project of Shagrath. He is also the rhythm guitarist of the heavy metal band Chrome Division.
Shagrath also sports extensive tattoo work. This work includes the word Shagrath across his stomach, various arm tattoos which cover his arms as well as extend to his upper chest.
In August 2008, Shagrath announced his engagement to actress Christina Fulton.
In late 2009, Shagrath joined forces with King ov Hell (ex-bassist of Gorgoroth) and formed the band Ov Hell. In February 2010 the band released their first album entitled "The Underworld Regime".
