NASHVILLE, Tenn. (AP) — Country star Jason Aldean says he hopes that healing can start for those affected by a mass shooting at a Las Vegas music festival in his first interview since the October shooting. Speaking on NBC's "Today" show, Aldean, who was on stage when a gunman opened fire on the crowd at the Route 91 Harvest Festival, said that he initially thought a speaker had blown when he heard a sound like a crackling over his in-ear monitors.
