The Killers promise concert surprise

The Killers have told fans to expect a number of surprises for their upcoming concert directed by Werner Herzog for the 'American Express Unstaged' music series.

The Killers have promised a host of surprises for their upcoming concert directed by Werner Herzog.

The group are collaborating with the legendary director for a September 18 show for the 'American Express Unstaged' music series, which will coincide with the launch of their latest album 'Battle Born', and bassist Mark Stoermer says they are ruling nothing out.

He told Rollingstone.com: "[Werner] has ideas for someone crowd-surfing with a camera on. I think there's gonna be an animal involved. I'm sure it will be all done the right way."

The show will be live streamed from the Paradise Theater in the Bronx, New York at www.youtube.com/TheKillersVEVO and www.amexunstaged.com and frontman Brandon Flowers revealed the group were "honoured" to work with Werner.

He said: "We're so honoured to work with Werner Herzog. He's made some legendary films and we can't believe we got him to do this."

This will be the 11th performance within the innovative live stream music series and sees The Killers follow in the footsteps of performers including Usher, Jack White and Mary J. Blige.

Last October, Coldplay kicked off their European tour by streaming a concert live from the Plaza de Toros de Las Ventas in Madrid, directed by Anton Corbijn and watched by millions around the world.

The Dutch film director unleashed a host of artistic extras on the crowd throughout the show including a shower of paper butterflies during 'Hurts Like Heaven', confetti during 'In My Place' and balloons unleashed while the band played 'Lost'.
