The `Let England Shake` singer`s latest album deals with many different aspects of war through its lyrics, which required a great deal of research into historical conflicts, as well as listening to songs which conveyed grand themes in an understandable way, and PJ - short for Polly Jean - said she did so for a specific purpose.

She told NME magazine: "My whole proviso for the viewpoint of this album came about from wondering if there was such a post as Official War Song Correspondent. Because I know there are war poets and war artists, and I thought, `well, where are the was songwriters?`"

Polly added that while she is English, she didn`t want to focus her attentions on her home nation or her lifetime, and tried to include a series of different scenarios when planning the album, but also show how they are all intrinsically linked.

Describing some of the tracks, she added: "A song like `Written On The Forehead` is very much about modern day Iraq. `Bitter Branches`, again I feel, inhabits a different era, maybe in Russia, a different world. `In The Dark Places`, that might be Bosnia. You don`t know where it is. I was wanting to show the way that history repeats itself, really, and so in some ways it doesn`t matter what time it was, because the endless cycle goes on and on and on."

The album `Let England Shake` is released on February 14.
