Jason Aldean talked for the first time on camera about what exactly happened on stage the night of the Oct. 1 mass shooting in Las Vegas at the Route 91 Harvest Festival.

As he told Today in a sneak peek of an interview airing Tuesday (Nov. 14): “We wear in-ear monitors when we’re on stage. And really all you can hear is the music, and maybe your guys that can talk to you on microphones that are on side-stage or whatever".

"So when it first happened, I thought a speaker had blown,” he notes. “It just sounded like a crackling something. And so, I’m kind of looking around like, ‘What is that?’ Trying to figure out what it is. Then it stopped, so I was like, ‘All right, they must have got it fixed,’ so I kept doing my thing."

Aldean quickly noticed that the sound returned. “It lasted longer the second time,” he says. “I was actually kind of getting aggravated, so I looked over at the monitor guy on the side of the stage, as if to say, ‘What is that? Fix it.’ So when I turned and looked, my guitar player had run behind me and was telling me to move, like, ‘Let’s go,’ and my security guy was running on stage, telling me to run."

The superstar has since supported victims of the tragedy in various ways, with the latest being his appearance at Nov. 12's Country Rising concert in Nashville.

Aldean is expecting his first child with wife Brittany — his first son after two girls — in December. They'll name him Memphis, honoring the superstar's love of Elvis Presley.
