See Jason Aldean Recall Las Vegas Shooting in 'Today' Interview

"When it first happened I thought a speaker had blown," says the singer, who was onstage at Route 91 Harvest festival when gunfire erupted

Jason Aldean, who was onstage in Las Vegas as the deadliest mass shooting in U.S. history began, shares his thoughts in a candid interview on NBC's 'Today.'

Six weeks after the deadliest mass shooting in U.S. history, Jason Aldean is speaking out about the events that took place on October 1st in Las Vegas, while he was onstage closing out the Route 91 Harvest festival. The country superstar sat down for an interview with NBC's Today show, describing the horrific experience from the first moments he realized something was wrong to his thoughts since the massacre that rocked the country-music community and sparked a new gun debate in the U.S.

"So, when it first happened, I thought a speaker had blown is what I thought. It just sounded like a crackling something," Aldean said. "I'm kind of looking around like, 'What is that?' Trying to figure out what it is. Well then it stopped. So I was like, 'Alright, well they must have got it fixed.' And so I kept doing my thing, and then it happened again and it lasted longer the second time."

Realizing his guitarist had moved from his usual spot, the singer recalled, "I was actually kind of getting aggravated, so I looked over at my monitor guy that's on the side of the stage as if to say, 'What is that?' And, 'fix it.' And when I turned to look my guitar player had run behind me and was telling me to move, to 'let’s go,' and my security guy was running on stage telling me to run."

Hectic scrambling then led to what Aldean described as panic and pandemonium. But fully processing the tragedy, which claimed 58 lives and injured more than 500, has taken much more time, he explained. Getting back onstage at the Country Rising benefit in Nashville this past weekend was, he noted, "therapeutic." Since the shootings, he has returned to visit some of the injured in Las Vegas, adding that the nation can't move forward while divisiveness reigns.

"There's so much focus on politics and race and all these other things that just… at the end of the day, we're all in this together. We spend so much time arguing with each other and not enough time working on the issue that's really the problem," he said.

Also featured in the above video are fellow artists Dierks Bentley and Lady Antebellum. Lady A singer Charles Kelley recalled reaching out to Aldean in the wake of the shooting. "We're texting Aldean and he's texting us back, telling us, 'It was the scariest moment. I hope you never have to go through it,'" Kelley said. "I've never told him I loved him ever before and that was the first thing: 'I love you, buddy, so much. So glad you're safe.'"
