Nine Inch Nails leader Trent Reznor took the stage over the weekend in Las Vegas as part of his Tension tour, but his iPhone took center stage during one point in the performance, reports Mashable.

Reznor used the iPhone to FaceTime with Andrew Youssef, a concert photographer and Nine Inch Nails fan who is suffering from stage four colon cancer. Youssef had used Nine Inch Nails' tour as motivation to continue treatment and press on. Reznor learned about Youssef's situation and struck up a friendship with him.

Reznor told him he missed him, dedicating the Nine Inch Nails song "In This Twilight" to him. The crowd joined in, chanting Youssef's name.
