Coldplay reveal unseen footage of Richard Ashcroft collaboration as they launch online timeline

Frontman Chris Martin also confirms band are recording new album 'A Head Full Of Dreams'

Coldplay have launched an online timeline documenting the history of the group, including unseen video of the band’s rehearsal for Live 8 with Richard Ashcroft in 2005.

Entitled ‘The Coldplay Timeline’ the new feature on their official website charts their first rehearsal in 1998 right up to the present day.

The band also posted a note confirming they are currently recording new LP ‘A Head Full Of Dreams’.

Singer Chris Martin previously announced the name of their seventh studio effort last December.

At the time he said: “It’s our seventh thing and the way we look at it is like the last Harry Potter book or something. Not to say there might not be another thing one day but this is the completion of something.

“It was great to go from ‘Ghost Stories’ to go right back into the studio and now we’re making things that sound different. I have to think of it as the final thing we’re doing otherwise we wouldn’t put everything into it. Then we will go on tour.”

The band’s timeline includes behind-the-scenes footage from the ‘Yellow’ video shoot, never before seen photos from the band’s 1999 Manchester Roadhouse show and new photos from the 2014 ‘A Sky Full Of Stars’ video shoot in Australia.

The site also includes the first official Coldplay gigography, featuring every show that the band have played. Fans can also upload their own photos from any dates.

The band were recently favourites to headline the final night at Glastonbury before The Who stepped in.
