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".

 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 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. "

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.
