“ Burzum is a musical project by Varg Vikernes (originally under the pseudonym "Count Grishnackh"). It began during 1991 in Bergen, Norway and quickly became prominent within the early Norwegian black metal scene. During 1992 and 1993, Burzum recorded four albums; however, in 1994 Vikernes was convicted and imprisoned for the murder of guitarist Øystein "Euronymous" Aarseth and the arson of several churches.
While imprisoned, Vikernes recorded two dark ambient albums using only synthesizers, as he did not have access to drums, guitar, or bass. He has recorded two critically regarded albums since his 2009 release from prison. Burzum is considered one of the most influential acts in black metal; in Metal: A Headbanger's Journey, director Sam Dunn described Vikernes as "the most notorious metal musician of all time". Throughout his career, Varg has managed to create and maintain a very distinct sound unique to Burzum.
