Fans attending Swedish House Mafia‘s last destinations on the One Last TourMasquerade Motel in Los Angeles and Ultra Music Festival in Miami – will be experiencing a first-of-its-kind live, interactive aspect of the show. The Swedes along with Sony Xperia, have teamed up with the app LISNR and will be debuting the app for the performances. During the show, those with the app will have their phones triggered and be prompted to hold their phones in the air and help expand the visuals of the show into the crowd. The idea behind the app was another way to get people involved in the show, rather than just taking photos or videos. “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!” said Axwell. The app just needs to be running in the background of the phone in order for it to work, no internet connection is required. Grab download links below:
