Bjork examines her cells on the video for 'Hollow'

It’s just the feeling when you start thinking about your ancestors and DNA that the grounds open below you and you can feel your mother and her mother, and her mother, and her mother, and her mother 30,000 years back. So suddenly you’re this kinda tunnel, or trunk of DNA … All these ghosts come up so it ended up begin a Halloween song and quite gothic in a way … It’s like being part of this everlasting necklace when you’re just a bead on a chain and you sort of want to belong and be a part of it and it’s just like a miracle.

So said Bjork in an email to NPR on her new video. Made with biomedical animator Dave Berry, it’s a trip into the genes and cells that rule us. Like The Knife’s Forever, In A Year opera about the Darwin, its look inside ourselves is actually quite terrifying, an effect created by Bjork’s minimally powerful and dissonant backing. Fear in a grain of sand, and the tyranny of the selfish gene, it’s part of Bjork’s ‘Biophilia’ app/album/project, and it’s worth 5 minutes of your time.
