Varg Vikernes

Louis Cachet (born Kristian Vikernes; 11 February 1973), better known as Varg Vikernes (Norwegian: [ˈvɑrɡ ˈvìːkəɳeːs]), is a Norwegian musician, neo-Nazi, and convicted murderer. He released five albums under the name Burzum between 1992 and 1996, making him an influential figure in the early Norwegian black metal scene and its offshoot National Socialist black metal (NSBM). In May 1994, Vikernes was convicted of first-degree murder for the fatal stabbing of guitarist Øystein "Euronymous" Aarseth. He was also convicted of arson for the burning of four Christian churches in Norway. Vikernes was sentenced to 21 years in prison, and was released after having served 15 years.

A native of Fana in Bergen Municipality, Vikernes went on to join the band Old Funeral, in which he played guitar from 1989 until his departure in 1991. He recorded multiple tracks with the band, which were featured on the Devoured Carcass EP, as well as various compilation albums released years later. In 1992–1993, he also recorded bass for Mayhem's debut studio album De Mysteriis Dom Sathanas (1994).

In 1992, Vikernes, along with other members of the scene, was suspected of burning down four Christian churches in Norway. In August 1993, he fatally stabbed Mayhem guitarist Aarseth during an altercation at the latter's apartment, and was arrested shortly after. In May 1994, Vikernes was convicted of first-degree murder, church arson and possession of explosives. Vikernes has always maintained the killing was self-defense, and unsuccessfully argued for the charge to be reduced to voluntary manslaughter. He has denied committing the arsons, though he supported them. He was sentenced to 21 years in prison, the maximum penalty under Norwegian law. During his incarceration, Vikernes launched the neo-Nazi organisation Norsk Hedensk Front ('Norwegian Heathen Front'), had two books published, and released two ambient albums as Burzum. In 2009, he was released on parole. Afterwards, he moved to a small farm in Corrèze, France, with his wife and changed his name to Louis Cachet. In 2014, he was found guilty by a French court of inciting racial hatred against Jews and Muslims on his YouTube channel, Thulean Perspective, and sentenced to six months' probation.

Described by Sam Dunn as "the most notorious metal musician of all time", Vikernes remains controversial for his crimes as well as his political and religious views. He promoted views which combined Odinism and Esoteric Nazism, and openly embraced Nazism during the mid-to-late 1990s. He has continued to be associated with far-right politics.
