While in Arizona to play the Country Thunder Music Festival on Friday (4/6), Jason Aldean stopped by the Barrow Neurological Institute in Phoenix to visit patient Jovanna Calzadillas and her family. Jovanna is one of the survivors of last year's shooting at the Route 91 Harvest Festival in Las Vegas, and according to the hospital, she's made a "remarkable recovery" after being shot in the head at the festival. At first, Calzadillas's brain injury was so severe that "doctors in Las Vegas did not expect her to live."
