Radiohead have released hours of unheard music from around the time of their iconic 1997 album OK Computer after the band was hacked and asked to pay a hefty ransom.
Guitarist Jonny Greenwood announced the news on Twitter, writing that frontman Thom Yorke's minidisk archive, containing 18 hours of unreleased tracks during the sessions for OK Computer, was hacked, with the unnamed person reportedly demanding $150,000 (€132,000) to return the recordings.
The band have now made the 18 minidisc recordings, most of them around an hour in length, available to buy on Bandcamp for £18 (€20) with the proceeds going to the climate activists Extinction Rebellion.
He wrote: "We got hacked last week - someone stole Thom's minidisk archive from around the time of OK Computer, and reportedly demanded 150,000 on threat of releasing it.
"So instead of complaining - much - or ignoring it, we're releasing all 18 hours on Bandcamp in aid of Extinction Rebellion.
"Just for the next 18 days. So for #18 you can find out if we should have paid that ransom.
"Never intended for public consumption (though some clips did reach the cassette in the OK Computer reissue) it's only tangentially interesting. And very, very long. Not a phone download."
Yorke posted a message on the Bandcamp page which read: "We've been hacked.
"My archived mini discs from 1995-1998(?). It's not v interesting, there's a lot of it.
"If you want it, you can buy the whole lot here. 18 minidisks for #18. The proceeds will go to Extinction Rebellion.
"As it's out there, it may as well be out there. Until we all get bored and move on."
