Sigur Ros' last album was a little more abstract than most of their output, so maybe the Icelandic band has decided to re-incorporate some rock structure to their dream-like forms. Enter "Brennisteinn," a new song and music video from the band's forthcoming album "Kveikur." The thing is a monster. It's a very weird, exciting, morphing jam, but it's also louder than what fans may be used to -- of course, until it segues into Jonsi's floating bridge.

"Floating bridge" may be one of the topographical features on the planet the video's set on; the splashes of yellow and dripping silvers are strewn throughout the black-and-white landscape. Far out. The video was helmed by Andrew Huang, who -- and this may not surprise you -- recently directed videos for Bjork, for her "Biophilia" project.

"Kveikur" will be out June 18 via XL; it was produduced by the three members of Sigur Ros, Jón Þór Birgisson, Georg Holm and Orri Páll Dýrason and "sees the band shifting towards a more direct, aggressive sound," according to a release. The band will be supporting it, in part, while they're on tour, which is going on now. All dates are below.

Sigur Ros will also be stopping by "Late Night with Jimmy Fallon" tonight (March 22), and will be performing another new song then.

The band's last album, "Valtari," was released last year and made it to No. 7 on The Billboard 200.
