British musician Laura Mvula joinedColdplayfor the live performance in London at the BBC Maida Vale studios.

There is a whole other world of music behind that song that Ive just been discovering, Martin added.

Coldplay has never been cool.

Never will be cool.

Coldplay only have plans to release two more albums, Martin has said.
