Beloved English band Radiohead have released a huge collection of early OK Computer recordings, "never intended for public consumption", following an extortion attempt. 

According to social media posts by the band, frontman Thom Yorke's MiniDisc archive was hacked by a blackmailer who reportedly demanded $150,000 on threat of releasing it. 

Following the threat, the band have released the 18 MiniDisc recordings on Bandcamp for £18 with all money raised to be donated to climate charity  Extinction Rebellion.

"Instead of complaining - much - or ignoring it, we're releasing all 18 hours on Bandcamp in aid of Extinction Rebellion," guitarist Jonny Greenwood wrote. 

You'll have to move fast though because the recordings will only be available for the next 18 days.

"For £18 you can find out if we should have paid that ransom," Greenwood said.

"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. It's not a phone download. Rainy out, isn't it though?" he ended the post. 

OK Computer was released in 1997 and was the band's third studio album. 

The released recordings feature a full-band version of True Love Waits, a 12-minute version of Paranoid Android, Thom Yorke's demo recording of Karma Police and many unreleased or unfinished songs.
