Coldplay have revealed their seventh album, “A Head Full of Dreams”, will be released on December 4.

The band had previously hinted it could be their last, with Chris Martin describing it as “the completion of something”.

The upbeat, summery first single, “Adventure Of A Lifetime”, premiered on BBC Radio 1 and 2 on Friday.

Speaking to breakfast show host Nick Grimshaw, the band dropped hints about a headline appearance at Glastonbury. “We'd love to do it. That's our spiritual home, as a band,” said Martin.

All of Coldplay's previous albums have reached number one in the UK. Last year's intimate and melancholy “Ghost Stories” was the fourth best-selling record of 2014 worldwide, shifting 3.7 million copies in total.

The band went straight back into the studio after its release to record the follow-up, which Martin described as “a more colourful, more joyful sort of thing.” Recorded in Los Angeles, Malibu and London, “A Head Full of Dreams” will feature guest appearances from Beyonce, Noel Gallagher and Tove Lo.

Martin said the record had been “handed in” three weeks ago, after the band set themselves a deadline of finishing it before the end of the year.

The band is also planning to tour “early next year”, after only playing a handful of low-key shows to promote “Ghost Stories”.

Speaking to the BBC last year, Martin suggested the new record could be Coldplay's swansong. “It's our seventh thing, and the way we look at it, it's like the last Harry Potter book or something like that,” he told Zane Lowe. “I have to think of it as the final thing we're doing. Otherwise we wouldn't put everything into it.”
