It is sung by the Scala & Kolacny Brothers choir which is a rather bizarre name for one which consists completely of female singers, but there you go. The reason why it has that name is that the choir is run by two brothers, Stijn and Steven who conduct and accompany the Belgian choir. A haunting version of the song, no doubt, but now joined with a visual element.
The choir's interpretation of the song is different, to say the least and that is probably what attracted animator Alex Heller. This from Ms Heller herself - My name is Alex and I am trapped in the suburbs. I have absolutely nothing better to do than fantasize about other people's lives. That's a nice (possibly tongue in cheek) introduction but take her talents as an animator, a Belgian girl's choir and a Radiohead song beloved by many and you might think that you have a recipe for disaster.
Not so. The three come together seamlessly. I was absolutely blown away by this animation and it just goes to show (Mr Pixar) that you don't need a huge budget to produce an animation that has class, pathos and a real heart. We all want to belong but sometimes recreating ourselves to suit others will end in more rejection and hurt than if we just remain true to what we are. This wonderful short animation is composed of 1554 pictures, shot with a Nikon D60. Fantastic.
