Radiohead have announced that they will donate all proceeds from the sale of previously-unheard music to environmental activism group, Extinction Rebellion.
Some 18 hours of material was stolen by hackers from frontman Thom Yorke's archive, who then requested a ransom of around 150,000 US dollars.
But the band has now released the 18 hours of music on bandcamp for £18, with all proceeds being given to the climate change protest group.
Radiohead responded to the hacking incident, saying “if you want it, you can buy the whole lot here”.
They wrote: “We’ve been hacked. My archived mini discs from 1995-1998.
“It’s not v interesting [sic]. There’s a lot of it. If you want it, you can buy the whole lot here.”
They added: “As it’s out there, it may as well be out there until we all get bored and move on.”
All of the music is now being sold via music website bandcamp
The minidisks include unheard music from Radiohead’s third album OK Computer, which was orginally released in June 1997.
Extinction Rebellion thanked the band, saying the money would allow the group to continue its “powerful movement of non-violent civil disobedience”.
“The climate and ecological emergency demands courage, truth-telling and generosity like never before,” the group said in a statement.
“We are so grateful to Radiohead for showing us how that’s done, both now - and in the lead up to the April rebellion. Words are inadequate but actions do change the world."
Extinction Rebellion caused a stir after talkRADIO revealed their plans to fly drones at Heathrow Airport in protest at a planned third runway.
They are set to stage the protest on June 18, with a further 10 days of disruption planned from July 1.
