Oscar and Grammy award-winning composer Hans Zimmer and acclaimed rock band Radiohead are collaborating on a song for the prequel to BBC's ocean-based documentary series, Blue Planet II.

Titled (ocean) bloom, it is an "orchestrally re-imagined version" of a song from the Grammy-winning band's 2011 album The King of Limbs, Bloom. It will be recorded with the BBC Concert Orchestra at London's AIR studios.

A snippet of the tune will be released online on Sep 26, while the whole song can be heard in full in a five-minute prequel of Blue Planet II released on Sep 27.

Radiohead frontman Thom Yorke says of the project: "Bloom was inspired by the original Blue Planet series so it's great to be able to come full circle with the song and re-imagine it for this incredible landmark's sequel. Hans is a prodigious composer who effortlessly straddles several musical genres so it was liberating for us all to work with such a talent and see how he wove the sound of the series' and Bloom together."

Zimmer, whose works span movies ranging from Disney animated film The Lion King (1994) to recent war epic Dunkirk (2017) says: "Bloom appears to have been written ahead of its time as it beautifully reflects the jaw-dropping lifeforms and seascapes viewers are introduced to in Blue Planet II. Working with Thom, Jonny and the boys has been a wonderful diversion and it's given me an interesting peek into their musical world. They've been incredible to work with and I hope everyone likes the track."

The seven-episode Blue Planet II series, a sequel to the acclaimed The Blue Planet from 2001, is set to air on on BBC Earth (StarHub Channel 407) and BBC Player later this year. The soundtrack to the television show is scored by Zimmer and fellow composers Jacob Shea and Dave Fleming.
