Sixteen years after The Blue Planet debuted, BBC Earth has created a sequel series that will use new science and new technologies to showcase the current state of life within our oceans. This extended trailer for Blue Planet II is narrated by Sir David Attenborough, and set to an orchestral track by composer Hans Zimmer and rock band Radiohead. It’s a reworking of the song ‘Bloom’ from Radiohead’s 2011 album The King of Limbs. Via NPR:

Yorke says that the original version of the song was actually inspired by the BBC’s first Blue Planet series, which ran in 2001. “So it’s great to be able to come full circle with the song and reimagine it for this incredible landmark’s sequel.”

Vox looks into How Hans Zimmer and Radiohead transformed ‘Bloom’ for Blue Planet II, retitled ‘ocean (Bloom),’ and their use of an orchestral trick called ‘tidal orchestra.’ The sound is “created by instructing each player to play their notes only if the person next to them isn’t playing.”

And here’s a version of Bloom that was filmed during a live studio performance for The King of Limbs: live From the Basement:
