Context paragraphs:
Burzum: Burzum ( ; ] ) is a music project that began in 1991 by the Norwegian musician and writer Varg Vikernes.  It became a part of the early Norwegian black metal scene and is considered to be one of the most influential acts in black metal.

Varg Vikernes: Varg Vikernes (] ; born Kristian Larsson Vikernes, 11 February 1973; legally Louis Cachet) is a Norwegian musician and writer.  In 1991, he founded the one-man music project Burzum, which is considered one of the most influential black metal acts.  Three years later, he was convicted of murder and arson, and subsequently served over 14 years in prison.

Gerard Way: Gerard Arthur Way (born April 9, 1977) is an American singer, songwriter, musician, and comic book writer who was the lead vocalist and co-founder of the rock band My Chemical Romance from its formation in September 2001 until its split in March 2013.  His debut solo album "Hesitant Alien" was released on September 30, 2014.  He also wrote the comic mini-series "The True Lives of the Fabulous Killjoys" and the Eisner Award-winning comic book "The Umbrella Academy".

Dauði Baldrs: Dauði Baldrs (English: "Baldr's Death" or "The Death of Baldr") is the fifth album by the Norwegian one-man band Burzum.  Unlike Burzum's previous work, which was mostly black metal, this is a dark ambient album.  It was recorded using a synthesizer and a normal tape recorder by Varg Vikernes while he was in prison, as he was not allowed to have any other instruments or recording equipment.  It was completed in a few months due to his limited access to synthesizers, which was also the case with the following album, "Hliðskjálf".

Umskiptar: Umskiptar (Old Norse for "Metamorphosis") is the ninth studio album by the Norwegian one-man band Burzum, released on 21 May 2012 through Byelobog Productions.  It has been described by Varg Vikernes as a "return to the roots", with a priority on atmosphere.  The album's lyrics are taken from an Old Norse poem entitled "Völuspá".  The album was leaked two months before its release date, due, according to Vikernes, to a former PR agent of his having "sent promotional copies of the entire album to left wing extremist magazines" without his knowledge or consent.

Hliðskjálf (album): Hliðskjálf is the sixth album by Norwegian one-man band Burzum.  This album was the second to be recorded by Varg Vikernes while he was imprisoned for murder and arson and also Burzum's second ambient album. " Dauði Baldrs" and "Hliðskjálf" were created with synthesized instruments as he was not allowed any other instruments while being imprisoned.  The first pressing of its vinyl format release was pressed on a shiny burnished color reminiscent of gold, instead of the standard black color vinyl record.

Mayhem (band): Mayhem is a Norwegian black metal band formed in 1984 in Oslo.  They were one of the founders of the Norwegian black metal scene and their music has strongly influenced the black metal genre.  Mayhem's early career was highly controversial, primarily due to their notorious live performances, the 1991 suicide of vocalist Per Yngve Ohlin ("Dead") and the 1993 murder of guitarist Øystein Aarseth ("Euronymous") by former member Varg Vikernes ("Count Grishnackh"), of Burzum.

The Ways of Yore: The Ways of Yore is the eleventh studio album by Norwegian musical project Burzum, released on 2 June 2014 by sole member Varg Vikernes' label Byelobog Productions.  The album retains the ambient and medieval music sound Vikernes started with Burzum's previous album, "Sôl austan, Mâni vestan", albeit introducing vocals.

Satan rir media: Satan rir media ("Satan Rides the Media") is a 1998 Norwegian documentary by Torstein Grude.  The film covers the controversy that surrounded black metal musician Varg Vikernes in the early 1990s, who not only has been tied to a series of church arsons in Norway, but received widespread media attention for the murder of Mayhem band member Øystein "Euronymous" Aarseth.

Filosofem: Filosofem (Norwegian for "philosopheme") is the fourth studio album by Norwegian black metal solo project Burzum.  It was recorded in March 1993 and was the last recording before Varg Vikernes' imprisonment (16 May 1994); the album was not released until January 1996, however.  A music video was made for the song "Dunkelheit", which received airtime on both MTV and VH1.
