The band's frontman Brandon Flowers recently gave an interview to Zane Lowe on BBC Radio 1 and said the group is back together after its stars had been off working on their own solo material.
Asked if they have any new tracks, he said: 'We have about four or five. We've put them up on the board and they're sounding good. We think they're strong.'
The Killers will be playing the Hard Rock Calling show on June 24 in London and Flowers said they are nervous about the gig.
He said: 'Those first gigs will definitely be nerve-wracking.'
