Coldplay, who previously admitted they thought fans were bored of their sound, have been penning experimental jazz and rave tracks for their next album.
Coldplay are recording a rave song.
Drummer Will Champion has been experimenting with different equipment and speeds while the group are in the studio - working on the follow-up to last year's 'Viva La Vida or Death and All His Friends' album - and has come up with a 168 beats-per-minute dance track.
A source said: "The lads are still on a creative roll in the studio and Will is bringing loads of ideas to the table.
"He's got a new drum machine and has been having a lot of fun pushing it to the limits. The most recent offering is turbo-charged, to say the least, but the lands have been having a great time working with it."
In addition to the rave track, Will has also been helping compose an experimental jazz tune for the group.
The source added to Britain's The Sun newspaper: "Will has got a track in seven-four time that he's working on. Most rock music is based around the standard four-four time signature. It's only the most adventurous of jazz people who compose anything with such an irregular beat. But he's pressing forward with it."
Coldplay's new direction may have come about because they were growing increasingly worried fans were getting bored of their branch of melodic indie rock.
Guitarist Johnny Buckland - who plays in the group alongside Will, singer Chris Martin and bassist Guy Berryman - recently revealed: "We ended up doing much more touring than we originally planned so there's no time to do proper justice to a new project. And anyway people may need a bit of a break from us. We've got a lot of ideas but we want to find a new way to go and that may take some time." |
