Question: Where is the band that came out with the album "Isa" currently based?

full_context: Document 1: In Sorte Diaboli: In Sorte Diaboli (Latin for "In league with the devil") is the eighth studio album by Norwegian symphonic black metal band Dimmu Borgir, released in 2007. It is the band's first concept album. A site on the Nuclear Blast website was created for "In Sorte Diaboli", in which a new promotional photo can be seen and an audio sample can be heard. This would be the last album by Dimmu Borgir to feature ICS Vortex, Hellhammer and Mustis.
Document 2: Isa (album): Isa is the eighth full-length studio album by Norwegian metal band Enslaved. Several tracks segue continuously into one another and the majority of compositions are composed of multiple interlocking movements.
Document 3: N (album): N is the fifth full-length studio album by Finnish melodic death metal band Norther. The album was released through Century Media Records on February 13, 2008 for Finland, and other dates in February for other parts of Europe. The track "Frozen Angel" from their previous EP, "No Way Back", was re-recorded for the album. "We Rock" and "Frozen Angel" have been made into music videos. This is also the last Norther album to have founding member Petri Lindroos on vocal and guitar duties.
Document 4: Ivar Bjørnson: 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.
Document 5: Enslaved (band): Enslaved is a Norwegian extreme metal band formed by Ivar Bjørnson and Grutle Kjellson in Haugesund in June 1991. They are currently based in Bergen, Norway. Though the band's lineup has changed many times over the years, Bjørnson and Kjellson have been the sole constant members, and the lineup remained the same from 2004 to 2016. Following their 25th anniversary world tour, keyboardist/guitarist/vocalist Herbrand Larsen departed from the band after 12 years and six albums. He has since been replaced by Håkon Vinje.
Document 6: Between Two Worlds (I album): Between Two Worlds is the debut album by Norwegian black metal supergroup I. The album was recorded at the Lydriket Studio and later mixed by Peter Tägtgren at the Abyss studio. The album showcases Abbath's straightforward metal style rather than his black metal style. The album displays a clear influence from classic metal bands, which although present in Abbath's primary band Immortal, is here the sole focus of the music. A limited edition digipack was released, which includes three bonus tracks. A limited edition metal box was also released, also featuring the three bonus tracks, and was limited to 1000 copies.
Document 7: Universal (Borknagar album): Universal is the eighth full-length album by the Norwegian metal band Borknagar. It marks the return of guitarist Jens F. Ryland. The band's former vocalist ICS Vortex performed vocals on the track "My Domain". The album was intended to be released in the fall of 2009, but the release date was postponed as a result of a label decision. It was released on 22 February 2010 in four formats: a regular jewelcase CD, a limited digipack which includes a bonus disc, a CD box with extras, and a gatefold LP with double vinyl.
Document 8: 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.
Document 9: Emperor (band): Emperor is a Norwegian black metal band formed in 1991, regarded as highly influential by critics and emerging black metal bands. The group split up in 2001, but reunited from 2005 to 2007 for a few festival dates and brief US tours, and again reunited in 2013 to 2014. The group was founded by Ihsahn (guitar/vocal) and Samoth (then, drums).
Document 10: Return to Yggdrasill: Return to Yggdrasill, in addition to being a song off the band's 2004 "Isa" album, is also a 2005 DVD release by the Norwegian metal band Enslaved, consisting primarily of concert footage recorded in Bergen, Norway. The material on this set focuses primarily on songs from the preceding album, "Isa".
Document 11: The Older Ones: The Older Ones is the first compilation album by Norwegian blackened death metal band Old Funeral, which was made up by key players in the Norwegian black metal scene, including bassist/vocalist Olve "Abbath" Eikemo (Immortal), guitarist Harald "Demonaz" Nævdal (Immortal) and guitarist Kristian "Varg" Vikernes (Burzum). By the time this album was released, the members had already gone their separate ways, with Immortal a going concern for Abbath and Varg in jail.
Document 12: Ulver: Ulver (Norwegian for wolves) are a Norwegian experimental musical collective founded in 1993, by vocalist Kristoffer Rygg. Their early works, such as debut album "Bergtatt", were categorised as folklore-influenced black metal, but have since evolved a fluid and increasingly eclectic musical style, blending genres such as rock, electronica, symphonic and chamber traditions, noise, progressive and experimental music into their oeuvre. 1997 marked their international debut with the release of their third album "Nattens madrigal" through German label Century Media. However, following discord with the label, Kristoffer Rygg formed his own imprint Jester Records in 1998. British composer and multi-instrumentalist Daniel O'Sullivan joined the collective in 2009, and the band performed some of their first live concerts in their 15-year lifespan, including the prestigious Norwegian National Opera.
Document 13: Immortal (band): 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.
Document 14: 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.
Document 15: True Norwegian Black Metal – Live in Grieghallen: True Norwegian Black Metal – Live in Grieghallen is Gorgoroth's first full-length live album, released by Regain Records. It was recorded live in the studio at Grieghallen Lydstudio in Bergen and Threeman Recordings in Stockholm. The songs on the album represented the most commonly played songs in Gorgoroth's live set. The cover design by Magnus Wohlfart was radically different from the previous three full-length albums, being more reminiscent of the cover of the album "Under the Sign of Hell" (1997). Most of the album was recorded before the departure of vocalist Gaahl and bass guitarist King ov Hell, who had intended on using the band's name and assets. The bass guitar for this album (originally performed by King ov Hell) was later re-recorded by guitarist and band founder Infernus. Infernus dedicated the album to the late Jon Nödtveidt of Dissection.
