The group is currently working on the follow-up to their 2008 album Viva La Vida, and Martin said the new album is almost completed.
He told UK radio’s Xfm: 'We're waiting for a drumbeat from [drummer] Will tomorrow. Once Will's decided which beat he wants to do on a song – which we don't even have a title for yet – that will drastically speed up the process.'
Speaking on Xfm's evening show, the band confirmed that the untitled album, which is due for release next year, will be “more about the guitars than the piano”.
Talking about guitarist Johnny Buckland, Martin said: 'He's really doing great stuff, it's very exciting to stand next to it.'
