Emerging from the viscous black shadow of a backstage tent, The Killers frontman Brandon Flowers leads the camera on an exhilarating journey to the band’s sold out headline show at British Summer Time festival in Hyde Park, London. “The walk to the stage is really a moment of transformation,” says long-term The Killers collaborator and director Giorgio Testi. “It’s when the artist changes their off-stage persona to an on-stage one.”

Flowers’ marshmallow pink showman’s jacket weaves through an endless entourage of backing singers, technicians, photographers, artist liaisons, stage crew and security. Each moment in this one shot, behind-the-scenes short is ecstatically elongated by the Testi’s slow-motion filming technique. The director has built a star-studded portfolio of electrifying and award-winning films for Nile Rodgers, Savages, Blur, Oasis, London Grammar and The Rolling Stones. “There’s a lot of work that goes on around concerts," says Testi. “It’s like a plane about to take off. Once you walk on stage you can’t go back until you’re airborne."

The festival’s Great Oak Stage looms in the distance like a behemoth, dampening the screaming voices of 65,000 faceless Londoners. “It’s a sacred moment. You can feel the adrenaline and the tension,” says Testi. “I’ve done quite a few live shows in my career. Whether it’s a big or small gig you always feel the pressure as you approach showtime. But Brandon, cool as always, makes it look so easy.”
