Sigur Rós played the title track to their new album, "Kveikur," on "Late Night with Jimmy Fallon."

Sit back and enjoy this Sigur Rós musical tale of a ballet dancer and her father. The ending will blow your mind.

Like most Sigur Rós videos, the Icelandic band's video for "Seraph" is odd and beautiful, and there's no Shia LaBeouf peen this time.

Whenever one watches a Sigur Rós video, one goes into it knowing that they're going to feel transformed to a light but meaningful state, and that what they're about to see will be weird and may, in fact, include some Shia LaBeouf peen.

(CANNOT.

I don't know about you, but whenever I want to get heavy -- I mean really HEAVY -- I throw on some Sigur Ros.
