The band was recently the victim of hackers who stole the music from singer Thom Yorke's private archive.
Those behind the hack had demanded $150,000 (€133,000) in return for not publishing the tracks, but Radiohead went on the offensive, announcing, "We're releasing all 18 hours on Bandcamp [a music-sharing site] in aid of Extinction Rebellion."
No surprises?The band says it never intended to release the tracks, but that fans would now be able to purchase the music for 18 pounds ($23.00, €20.20) over the next 18 days, to "find out if we should have paid that ransom."
Extinction Rebellion, which recently gained attention for days of climate-change protests it orchestrated in London, said, "We thank Radiohead for supporting us so that we can continue to build our already far-reaching and powerful movement of non-violent civil disobedience."
