It has since sold over 100,000 copies in the United States; the first album under Nuclear Blast to do so; and debuted on the "Billboard" 200 chart at number 169.

Immortal is a black metal band from Bergen, Norway, founded in 1991 by frontman and bassist Abbath Doom Occulta (Olve Eikemo) and guitarist Demonaz Doom Occulta (Harald Nævdal).  The pair worked with various drummers (including Grim, Armagedda and Hellhammer), and were later joined by current drummer Horgh (Reidar Horghagen) in 1996. Ivar Bjørnson (born November 27, 1977 in Etne) is a Norwegian composer/guitarist for the progressive black/viking metal band Enslaved.  He is, along with Grutle Kjellson, one of only two founding members left in the current line-up, being only 13 years old at the time of the band's formation in 1991.  Bjørnson and Grutle Kjellson performed in a death metal band called Phobia in 1989.  The two decided that they wanted to form a new band in a more black metal style, and after discovering their shared fascination with Norse mythology, this set the groundwork for Enslaved.  Beyond his duties on guitar, he writes almost all of the music for Enslaved as well as much of the lyrics.  He has said that "When we started Enslaved we wanted to have the same level of commitment to something spiritual as our contemporaries in black metal [have with] the Satanic side.  The dark destructive part of black metal didn't seem right because we didn't have any commitment to any Satanic ideology."  He contributed keyboard/synth work to Borknagar's first three albums and synth/piano work on the Gorgoroth albums "Incipit Satan" and "Destroyer" under the name "Daimonion"; and also produced the first demo from black metal band Orcustus. All Shall Fall is the eighth studio album by Norwegian black metal band Immortal.  The album was released in Europe on September 25, 2009, and in the US on October 6, 2009.

Satyr (born Sigurd Wongraven on 28 November 1975) is the vocalist, lead and rhythm guitarist, bassist, and keyboardist for the Norwegian black metal band Satyricon.  He was a founding member of Satyricon (although the band had been around for a short length of time as Eczema without him) and have so far released eight albums, two demos, and a live DVD.  He has also contributed to other bands such as Darkthrone, Eibon, Storm, Thorns, Black Diamond Brigade and Wongraven.  About black metal, he stated "It, black metal, doesn't necessarily have to be all satanic as long as it's dark."  He has recently been endorsed by ESP Guitars. Marcin "Martin" Rygiel, (born 30 April 1983 in Krosno, Poland), is a Polish musician, best known as the former bass guitarist of the technical death metal band Decapitated from 1997 to 2007, leaving several months before their hiatus.
