Jason Aldean, who was on stage during the shooting, has put out a statement on Instagram.
"Tonight has been beyond horrific," he began.
"I still dont know what to say but wanted to let everyone know that me and my crew are safe," Aldean added. "My Thoughts and prayers go out to everyone involved tonight."
Brittany Aldean, Jason's wife, also confirmed she was safe following the shooting.
President Donald Trump was among the first to chime in, which was soon followed by Barack Obama and Hillary Clinton.
The country music world has been particularly sympathetic. Brad Paisley, Sheryl Crow, Big & Rich and more chimed in while Jake Owen and Chris Young were actually in attendance and tweeted out their experiences.
The celebrity world followed.
Details on the gunman—dead on the scene from a self-inflected gunshot wound—and the many victims are still pouring in.
We'll all need some goodwill on Twitter to keep going.
