Coldplay will play their biggest ever live dates
Coldplay have revealed they are returning to the studio with producer Brian Eno.
Since releasing Viva La Vida Or Death And All His Friends last year the band have embarked on an extensive world tour.
They have though, found time to work on new material.
Speaking to the band's official website bassist Guy Berryman said: "When we get back into the studio we'll be able to pick up where we left off with Brian."
He added: "We've worked on a few ideas in soundchecks."
As previously reported Coldplay will play a series of huge shows this September, including two dates at London's Wembley Stadium.
"We actually had a big production meeting today [2 April] with all of the relevant people involved and went over all the plans," said Berryman.
"We've got some computer renderings of all the ideas and we're all quite excited about how it's looking - we're just working through a few logistical difficulties with some of the ideas that we've got.
"All we've really got to do is take the same principles of the arena show and make things a bit bigger.
"I think they're probably going to be some of the best shows we'll ever do."
The bassist also hinted that fans can expect a few surprises in the set list come this summer.
"We've been trying to dust the cobwebs off here and there, because the idea is that for the bigger shows in the summer we'll play for a little bit longer - so we've been digging out some of the older songs which we haven't played for a while.
"We played Sparks today and we've been playing Rush Of Blood To The Head, Warning Sign and White Shadows."
Berryman was speaking having returned from extensive touring in Malaysia, New Zealand and Australia, where they made an unlikely friend in cricketer Shane Warne.
"I think he contributed more in spirit than in musicality!" said Berryman. "He's such a great guy, though. He's become a very good friend of the band."
