The band performed "Kveikur" on NBC late night talk show Late Night with Jimmy Fallon during the tour on 22 March 2013. During the former legs of the tour, Kveikur tracks "Kveikur", "Yfirborð", "Hrafntinna", and "Brennisteinn" had been played live.
The North American leg of the tour, which occurred in March and April, was supported by Oneohtrix Point Never and Tim Hecker. The 82-date tour visited Australia, South-East and East Asia, Europe and North America. The band embarked on the Sigur Rós World Tour in late 2012 and throughout 2013 in promotion of Kveikur. The video is also notably the band's first lyric video for a song since the band's formation in 1994. The band also released an accompanying lyric video for the song on their YouTube channel on 2 April.
The song was also released early for download on iTunes through Kveikur's listing, before the album was released in June. " Ísjaki" was released as a radio-only single from the album a month later on 24 April 2013. The eight-minute music video for the song, directed by Andrew Huang, was released three days earlier during Kveikur's unveiling on March 22. " Brennisteinn" was released as the lead single from Kveikur on 25 March 2013. On the 11th of June the album was made available to stream live in its entirety online. An EP, entitled Brennisteinn and featuring lead single "Brennisteinn" and two Kveikur cuts "Hryggjarsula" and "Ofbirta", was also released on the same day to ticket holders of North American dates on the Sigur Rós World Tour. The album's details, such as artwork, tracklist, and release date, were publicly announced, along with dates for the band's corresponding tour. Kveikur was officially unveiled by the band and label XL Recordings on 22 March 2013. All tracks are sung in Icelandic, although Yfirborð contains some reversed words at the start, which can be considered Hopelandic. The band has described the album's sound as "more aggressive" than any of their previous works.
Track listing No.Kveikur sees a new direction taken by Sigur Rós, both musically and thematically. The cover depicts Jónsi's sister Inga Birgisdóttir as a baby. The tracks "Hafssól" and "Von" were later re-recorded with different arrangements, the former released as a B-side to the Hoppípolla single and both appearing on 2007's Hvarf/Heim. The last track starts with six minutes and fifteen seconds of silence, then consists of a portion of "Myrkur" played backwards, hence the name of "Rukrym." The sixth track consists of 18 seconds of silence, and gave name to Sigur Rós's official website, 'eighteen seconds before sunrise'. In 2005, Von and Ágætis byrjun were declared platinum albums in Iceland, signifying domestic sales of over 5,000. Following the band's popular international releases, Ágætis byrjun and ( ), it was re-released in the United Kingdom in 2004, and in the United States a month later. In the first year following its release, Von sold only 313 copies in Iceland. Von was originally released in Iceland to positive reviews from critics, but went relatively unnoticed abroad. In exchange for recording time, Sigur Rós painted the studio they recorded in. The band considered scrapping the final result, but decided not as it would have made the process too long. Production lasted over two years, and the end result sounded significantly different from the original recordings. Von ( Icelandic pronunciation: , Hope) is the debut studio album by Icelandic post-rock band Sigur Rós, released on 14 June 1997 by Smekkleysa Records.
