This British documentary shows a meeting between Icelandic musician Björk and English naturalist and broadcaster David Attenborough, partially shot at the Natural History Museum in London. Having Biophilia, the singer’s most recent work, as a staring point, this film talks about the interaction between music, nature and technology, in addition to the unknown powers of sound. The documentary also includes an interview with American writer and neurologist Oliver Sacks reflecting on the effects of music on the brain.
