Sigur Ros have unveiled the brand new video for their single 'Fjögur píanó', which features Hollywood actor Shia La Beouf baring all for the Icelandic band's new release.

Obviously, it's a lot more credible and arty than the star of Transformers in the buff with the video being the latest installment in Sigur Ros's Mystery Film Experiment series.

Director Alma Har’el helmed the shoot, creating the video on a limited budget and submitting his idea to the band.

Sigur Ros bassist Georg Holm is a big fan, stating: “We really had no idea what to expect from Alma. Originally she was going to film us on super 8 in Iceland all playing the piano lines from the song, but then she rang and said she’d met Shia Labeouf and they’d changed the idea, that was the last we heard of the concept and she told us nothing about what was going on.

“At first I didn’t know what to make of the video, because it is so full of ideas and confusion. But now I completely love it. It seems to have no beginning and no end, and just makes you think about what might and might not be going on. It’s a puzzle and I think it’s absolutely amazing.”
