Radiohead frontman Thom Yorke has shared a new solo rendition of the band’s “Bloom” for a Greenpeace ad.

The advertisement was created for Shark Awareness Day and is titled “The Lonely Shark.” In the clip, Yorke reworks “Bloom” into a haunting, piano-driven track. Clocking in at just under two minutes, the song soundtracks a moment when two sharks that get separated when one of them is caught by a fishing boat.

“In the last 50 years the global shark population has plummeted by 70%,” the video’s description reads. “Sharks are being wiped out by overfishing for profit. But our oceans can recover if we protect them.”

Thom Yorke has been pretty busy collaborating with bandmate Jonny Greenwood and Sons of Kemet’s Tom Skinner in their band, The Smile. Back in May, they shared their debut album, A Light for Attracting Attention. The album is a pretty stunning collection, featuring performances from the London Contemporary Orchestra. It also boasts some amazing contributions from UK jazz player Byron Wallen, Theon and Nathaniel Cross, Chelsea Carmichael, Jason Yarde, Robert Stillman, and more.

The record opens up with Thom Yorke’s lyricism at the lead, delivering lines like, “we are the same.” Revolving primarily around Yorke and Greenwood’s playful vocal and guitar riffs, with the driving force of Skinner’s percussion, the seasoned album channels some Radiohead sounds, while paving its own sonic territory entirely.

Yorke is also no stranger to solo reworkings. In addition to this new rendition of “Bloom,” Yorke has previously shared or performed solo renditions of “Bodysnatchers,” “Exit Music (For a Film)” and “Creep.”
