The long awaited follow up to Battle Born has taken five years, but along with five years of waiting also came with five years of birthdays for the band and as frontman Brandon Flowers approaches his fortieth birthday, the desire to make a “grown-up record” also comes with it.

“I put more of an effort to be more personal on this record,” said Flowers and this becomes quite clear when looking at the subjects this album tackles including his wife's PTSD which are sang about in the song, “Some Kind of Love.”

Flowers talks about how his wife, Tana Mundkowsky, heard the emotional single and sobbed.

“It's really emotional,” he says. “I played that for her, and she just sobbed.”

This new album is produced by Jacknife Lee who's worked with a variety of artists in the past including U2, Weezer, R.E.M. and All Time Low. Flowers, along with drummer Ronnie Vannucci Jr., spoke highly of the producer who helped the band discover what kind of sound they wanted to create in their fifth album.

“We've worked with other people who might be better in their little corner of expertise or something like that, but as far as a broad strokes, holistic approach, it felt like he sort of understood the band and what we needed to achieve in making this record,” said Vannucci.

It was with Lee's help that Flowers was able to create a more “grown-up album, “I talked to him about wanting to make a more grown-up record. It's a scary word to say 'adult,' so we say 'grown-up … He pushed back a couple times on things, and that makes you reevaluate it. And sometimes he may have won, and sometimes maybe I won. But it's always good to have those conversations and conflicts.”

The Killers frontman recently compared this highly anticipated album to another Killers classic in Sam's Town in an interview with Entertainment Weekly.

In the interview, Flowers reminisced about the 10 year anniversary shows the band played for Sam's Town last fall. “Playing those gigs, I realized how cohesive an idea [Sam’s Town] was. That reminded us that we really want to make a record here, not just slap a bunch of songs together… I think we’ve done it again on this album.”

Wonderful Wonderful will be released on September 22.
