Third studio album by the Icelandic post-rock band. It is the only album where Jónsi sings entirely in the wordless lyrics of Hopelandic. A desire to elide meaning and allow the listener to bring their own interpretation to the music, extends to the eight songs, all of which are nameless. The music is broadly divided into two halves, divided by a critical 36 seconds of silence. The first half of the album being lighter and more optimistic, and the second half bleaker and more melancholic, culminating in the thundering climax of 'Untitled #8', the closing song of every Sigur Rós show since the song was written in 2000. This 20th Anniversary edition features a bonus disc of rarities and b-sides.
