The Swedish House Mafia, who are currently nearing the completion One Last Tour, their final farewell to their fans, are bringing us an interactive live show App which will bring them and their fans even closer together. In association with Sony Xperia, the Swedish House Mafia have partnered with LISNR and Sonic Notify to create an interactive free App that has been launched this week in time for their Masquerade Motel shows in Los Angeles & headline final shows at Ultra Festival Miami. During a special moment during the show, the LISNR app will be triggered into life via Sonic Notify’s sound technology prompting those with smartphones to hold their phones high into the air and become a part of the show as Swedish House Mafia’s state of the art visuals also take over the crowd. The concept behind the app is to bring fans TOGETHER as they near their final shows. To take a moment away from watching the show through the lens of a phone camera, hold them high in the air, and watch the show come to life across the audience. All will be filmed and a special video launched next week, powered by Sony’s Xperia Lounge who has been a partner on the group's One Last Tour. Axwell said: “We’re so excited to have found LISNR. LISNR will allow us to come together with our fans for a totally unique experience. Together, as one, for one last rave!” Attendees will not need an internet connection during the show. They simply download the app before they get there, and have the app open in the background of the phone during the show… it will be listening.
