Taking part in an impromptu FaceTime call is becoming an increasingly popular event during musical events. First we had Beyoncé taking an iPhone out of a fan’s hand and talking to her friend through FaceTime during one of her performances. Now we have the news that Nine Inch Nails’ frontman Trent Reznor invoked a FaceTime call with one of his friends during a show in Las Vegas. Although FaceTime itself is an extremely emotive way to communicate, the feeling was further heightened by the fact that the friend in question is currently suffering from terminal colon cancer.
