Brandon Flowers wasn't trying to "follow in U2's footsteps" with his previous musical offerings.

The Killers - also comprising of Dave Keuning, Ronnie Vannucci, Jr. and Mark Stoermer - are back with a new album, Battle Born, after a year-and-a-half hiatus.

Brandon has spoken about his band’s previous three albums, revealing the "fun" elements of 2008 record Day & Age.

"I think I pay too much attention to what people write. I'm doing better; I'm thinking less. That's why Day & Age is a fun record. We let our hair down," he told NME magazine.

"I wasn't worried about what critics might say or about trying to follow in U2's footsteps."

Brandon is proud of all his past music and feels that experimentation is key when it comes to producing great tracks. He didn't want Day & Age to be a carbon copy of previous album Sam's Town, which was released in 2006.

"Change is inevitable. We're not afraid of sounding the same, but we're also not afraid of embracing what's happening," he said. "This could have just as easily been Sam's Town Part Two. But when we got together, it just wasn't."
