They may seem an unlikely duo, but Björk and Sir David Attenborough could be this year's TV dream team.

The Icelandic singer-songwriter and BBC wildlife presenter have teamed up for a new Channel 4 documentary, Attenborough and Björk: The Nature of Music.

The film looks at the evolution of music and how technology might change the way we interact with it going forward.

Björk's music project, Biophilia, forms a central part of the documentary and explores how nature, music and technology meet.

Attenborough and Björk: The Nature of Music airs this Saturday at 7pm on Channel 4. Take a look at the trailer, below:
