The Killers are in London applying the finishing touches to their second album

The band's bassist Mark Stoermer told BBC 6 Music that the new record had a different sound. "It sounds like we've grown up a little bit as musicians, songwriters and as people," he said. "Overall it's still pop songs by a rock band, which is what we liked about ourselves before and I think other people did too. It sounds different, but it still sounds like us."

No official release date has yet been set for the follow up to 2004's Hot Fuss, but it is expected this year.
