Dan Deacon, who recently released the excellent “ America”, is known for making his live shows into real parties where he himself bonds with his audiences by encouraging improvised choreographies and generalised hedonistic mayhem. On more than one occasion, the bearded alchemist has encouraged his audience to raise their mobile phones as a light element to add to his show, but he has just given a surprising twist of the screw to the subject with the new app for iPhone and Android devices that he has just launched. Thought up by Deacon himself and created with the aid of Keith Lea, Patrick McMinn, Alan Resnick and Robert O'Brien, the application in question shoots off synchronised lights and sounds that vary depending on where you are in his concerts. And best of all is that you don’t have to be connected to a wi-fi or 3G network. Get an idea of the result by looking at this trailer-advertisement for the invention. The app is free and you can download it on iTunes Store and Google Play.
