Thom Yorke performs at the BBC Radio Theatre
Radiohead are beginning their world tour in Florida but are already planning a trip back into the studio.
The band will play four shows in the UK and two in Ireland in June.
It will be the first chance for most fans to see the band play tracks from their In Rainbows album.
But guitarist Ed O'Brien has revealed they will start recording new material as early as October, after the tour finishes in Tokyo.
He told Newsbeat: "It's the life blood of what we do, it's the thing that keeps you going.
"Because by the end of the tour, you're bored of what you're playing.
"You need more life and energy and the only way to do that is writing new songs."
Sadly for fans, O'Brien won't be pushed on when the new songs are likely to be unveiled.
He said: "It could be five years, it could be the end of this year, it's whether it's any good, that's the point.
"We've just got to do it and see if it's any good."
Before then, there's the small business of 48 live dates around the world
Singer Thom Yorke, who has a fear of flying, has admitted to being nervous.
O'Brien said: "Well he is also the frontman so it's heavier on his shoulders."
Radiohead played the new album in entirety to fans at a small gig in London in January and followed it up with two shows in one day for the BBC.
For O' Brien, it is the most important part of his job.
He said: "Personally speaking, it's the part I enjoy most of all. It's about music and direct communication.
"But it's also a very unreal existence. I can't get excited until we're doing the soundcheck on the first day and it really dawns on me what we're doing."
O'Brien also revealed his passion for Prince, who covered Radiohead's Creep at the Coachella music festival in California.
He said: "He is probably the greatest at the moment and I remember when he played the Brits two years ago.
"He made everybody, including us, look like amateurs.
"That's very flattering, he's the man.
"We'd love to do one of his songs but we'd probably murder it."
