Coldplay's Chris Martin has told NME that the band are striving to write their "masterpiece" with the follow-up to 2008's 'Viva La Vida Or Death And All His Friends'.

The frontman, speaking in the new issue of NME, on UK newsstands today (January 12), or available digitally, spoke about new songs including 'Princess Of China' and 'Every Teardrop Is A Waterfall', before admitting that he thinks the band can better their previous albums with the new effort.

"We still don't think we've delivered our masterpiece, so we're still trying to do it," Martin said. "As long as we feel like that and we're hungry… that's all that matters."

The band have again been working with Brian Eno and Marcus Dravs on the album.

"We were with Brian Eno for a long period just messing around," the singer said. "Now we're with Marcus, trying to turn that into something cohesive and under seven hours long. The worst mistake we could make, when we're the most Marmite-y of bands, would be to make a super-long thing".
