Kveikur (pronounced [ˈkveikʏr], fuse or candlewick) is the seventh studio album from Icelandic post-rock band Sigur Rós.

[11] The eight-minute music video for the song, directed by Andrew Huang, was released three days earlier during Kveikur's unveiling on March 22.

"[25] Gareth James of Clash praised the diversity of the music on Kveikur: "No two songs sound similar and, while Jónsi's vocals confirm that this is, really, the artist on the album sleeve, it is far from more of the same.

He stated, "With Kveikur, Sigur Rós seem to be shrinking from the light, away from the TV adverts and the Top Gear soundtracks, the Shia LaBeouf videos and the Daily Mail articles and the Hollywood movies.

And that's a good thing: for an alternative group from Iceland that veer between their native tongue and a made-up language they were becoming all too ubiquitous, and far less interesting with it – heck, when your own webstore starts selling candles 'specially developed to the band's olfactory specifications' it's definitely time for something new.

Well, here's the flipside, that long Scandinavian winter of frostbite and storms, of frozen rock and suicides, the Northern Lights cast overhead not dancing but shivering, particles undulating sinisterly against blackened skies and all the better for it.

This is a band whose frontman now scores Hollywood films (Cameron Crowe's We Bought A Zoo), whose household name status was confirmed when they recently cameoed on The Simpsons, who in recent years have dealt more in bright, bouncy orchestral indie (2008's Arcade Fire-ish Með suð í eyrum við spilum endalaust) than the dark experimental fare they made their name with.

"[37] Pitchfork also noted but excused this, praising the album for standing on its own: "Even if it doesn't have the same cultivated mystery or incapacitating demands of Ágætis byrjun or ( ), Kveikur is every bit a return to form, tapping into its predecessors' bottomless emotional wellspring for a Sigur Rós album that can be listened to casually or intensely, a collection that works as effectively as a spiritual experience and pop music, the essence of their overwhelming, widescreen grandeur conveyed with the immediacy of a 50-minute rock record.
