Partly filmed at the Natural History Museum in London, the documentary features an encounter between Icelandic singer-songwriter and musician Björk and English broadcaster and naturalist David Attenborough.

The documentary was inspired by the singer's eighth studio album Biophilia (2011), which was released as a series of apps which blends nature elements with musicology.

Collaborators in the project Scott Snibbe, Damian Taylor, and Andy Cavatorta appear in the documentary to talk about their role in the development of the album and the live show.

Despite the low ratings, the show received positive to moderate reviews from critics, who applauded the content of the documentary but, in some cases, criticised the interaction between Attenborough and Björk, which was considered "awkward" and "unlikely".

British-American neurologist Oliver Sacks was also reported to appear in the documentary, explaining "the extraordinary and beneficial effects music has on our brains".

[9] Director Hooper, whose father John had filmed Attenborough in different documentaries settled in Papua New Guinea, Mali and the Amazon rainforest, had stated: "There is an unexpected chemistry and fun between these two unique characters.

They were both great fun to work with; Bjork fizzing with ideas for the film and Sir David bringing his passion and knowledge".

[12] When a crowdfunding was created on Kickstarter to fund the release of Biophilia on Android, one of the reward available for the backers who would have pledged £120 or more was one early viewing DVD copy of the documentary.

After that, some frames focus on the Graduale Nobili who are singing the backing vocals to "Thunderbolt" on a cliff in front of the ocean in Iceland.

Footage from another rehearsal with the choir singing "Dark Matter" are shown before shifting to the encounter between Björk and Henry Dagg in a metal workshop.

Dagg had created the Sharpsichord, a solar powered cross between a harp and a barrel organ, which Björk wanted to incorporate in one song.

Scenes from the choir recording parts of "Crystalline" guided by Biophilia musical director Matt Robertson are shown.

Swinton tells how universe is made of patterns which are present in music but that we can't visualise, and how Björk wants to change that.

Grant explains how the Chladni plate works, and that he appreciates how Björk tries to bring a real meaning in her music by taking a "scientific and realistic approach" to it.

A performance of "Thunderbolt" is partially shown, during which the singer is seen wearing a dress by Michael van der Ham, along with a big red wig, while the Tesla coil plays on stage.

Swinton states that Biophilia "nature, music and technology come together" and that the Icelandic singer wants to develop a new kind of music-making which is "intuitive and accessible for everyone".

Björk's solution came with the diffusion of tablet computer, which touch screen the singer compares to a tambourine for its being spontaneous and instinctive.

She works with interactive media artist Scott Snibbe, who states that her aim is the turn music "into something full sensory".

After one year from the first show in Manchester, the Biophilia tour reaches the World Sacred Music Festival in Fes, Morocco, during which Björk is seen performing "Cosmogony".

The journalist praised Biophilia by affirming that "the whole idea was tantalisingly tangled" and that "any single aspect of Biophilia would have made for a fascinating documentary in its own right", while defining the parts with Oliver Sacks "touching" and concluding "from footage of spinning stars to shoals of fish to the snow-speckled hills above Reykjavík, from the sound of crackling electricity to Björk's soaring voice, there was a dreamy and unsettling evocation of awe.

In their conversations – on crystallography, the power of the human larynx, et al – Attenborough was in transmit mode, jabbing away with his index finger.

When the big man let rip on the notion that all "song" in the natural word is about sex, and so, therefore, is popular music, Björk reacted as we all did, I suspect, and looked a bit embarrassed.
