In his Icelandic releases, he was credited as Ásgeir Trausti.  But more recently in 2013 with his launching as an international artist, he has started using the mononym Ásgeir as a recording name.  Ásgeir performs with his own band, Ásgeir Trausti Band.  He also plays guitar in the Icelandic band The Lovely Lion. Slowblow is the final album by Icelandic band Slowblow, released in 2004.  Then lead singer, Kristín Anna Valtýsdóttir, in another Icelandic band Múm, and Amiina band member, Maria Huld Markan Sigfúsdóttir, made notable appearances on several tracks of the album. Mr. Silla & Mongoose is an Icelandic band consisting of fellow students Sigurlaug Gísladóttir and Magnús B. Skarphéðinsson.  The two met while studying visual arts at Iceland Academy of the Arts but did not form a band until after they had collaborated on their respective solo sets during Iceland Airwaves 2005 (2005) at a café by the name of Kaffi Hljómalind (also referenced in fellow Icelandic band Sigur Rós song named Hljómalind). Sólstafir is an Icelandic Post-Metal/Rock band, formed in 1995.  The band's name is the Icelandic word for crepuscular rays. Breiðamerkursandur is a "sandur" (e: glacial outwash plain) in southeast Iceland.  Sandur is the Icelandic word for sand and the whole area is mostly sand, although some vegetation is beginning to grow in the area.  The name of the sandur, Breiðamerkursandur, however means "broad forest sand", which suggests that the area may have been heavily vegetated in the early centuries of the Icelandic settlement. Fálkar is the soundtrack to "Falcons" ("Fálkar" is the Icelandic word for Falcons), which was directed by Friðrik Þór Friðriksson in 2002.  With 12 tracks, this album contains a variety of Icelandic artists, from Hilmar Örn Hilmarsson, who was in charge of the music composition of the soundtrack, to Mínus, Múm, and Daníel Ágúst Haraldsson (former member of Gus-Gus), among others. Ske is an Icelandic band whose origins can be traced back to 1992, when a band called "Skárren ekkert" was founded by Eiríkur Þorleifsson, Frank Hall and Guðmundur Steingrímsson, and joined by Hrannar Ingimarsson in 1998. Crouçie d'où là is the first album released by the Icelandic singer, Emilíana Torrini, released in 1995.  The title of the record is a play on words.  It is spelled as if it were a French phrase, but it is a homonym of the Icelandic word "Krúsídúlla" which means "cutie pie".  The songs include "Crazy Love" written by Van Morrison, "I" written by the Japanese group Pizzicato Five and "Miss Celie's Blues" (from the movie "The Color Purple"). "Hoppípolla" (] , "Hopp í polla" is Icelandic for "Hopping into puddles") is a song by Icelandic band Sigur Rós from their 2005 album "Takk...".  It was released as the album's second single on 28 November 2005.  The lyrics are mainly in Icelandic, with some nonsensical phrases, a "language" the band calls Vonlenska ("Hopelandic").  Written with spaces, the song's title would be "Hoppa í polla" (the "—a" in "hoppa" is not pronounced).  As with many of the band's songs, it was given a nickname in the early stages of writing.  "Hoppípolla" was "The Money Song", as the band was certain they had written a song which would have commercial success.  It is the band's most successful single, charting at #24 on the UK Singles Chart in May 2006.  It is considered the most well known song within its genre.  The single also features "Með blóðnasir", an instrumental coda to "Hoppípolla", which is also featured on "Takk..."; and a studio remake of "Hafssól", a song previously released on the band's 1997 debut album, "Von".  The title appears as "Hafsól" on the single.
