Jason Aldean is finally back on stage to carry on with his schedule and perform for his fans after the Las Vegas shooting earlier this month. The country singer brought his concert tour at the BOK Center in Oklahoma on Thursday.

According to an AP report, the country singer wanted to showcase a performance that the people in Las Vegas did not get to see due to the mass shooting. The recent concert marked his comeback to the music scene since the senseless killing at his Las Vegas show. Meanwhile, several survivors of the attack have joined Jason Aldean for his performance in Oklahoma.

Among those who came to witness his stage comeback were Ryan Guay and Linzee Freund, who were fortunate to have come out alive from the shooting incident. It is worth noting that thousands of concertgoers at the Route 91 Country Music Festival were stunned when a gunman opened fire from the 32nd floor of Mandalay Bay Resort and Casino on October 1.

Mass shooting in Las Vegas

The incident has left 58 people dead and about 500 individuals injured that made it the deadliest mass shooting in the modern U.S. history. Jason Aldean was then performing the last set for the music event when the gunfire started.

The singer quickly stormed off the stage and hid with his pregnant wife, Brittany, behind music equipment to avoid getting hit by flying bullets.

Several survivors said the shooting lasted for about 10 minutes before the first responders arrived on the scene.

Authorities identified Stephen Craig Paddock, 64, as the person responsible for the attack. He was found dead in his hotel room, where the police also discovered high-end weapons and explosives.

The incident has forced Jason Aldean to cancel his three-day show in California as a sign of respect to the victims and the families of those who did not survive the shooting.

He also appeared on "Saturday Night Live" to dedicate an emotional cover of "I Won't Back Down" by late Tom Petty.

A week after the mass shooting, the country singer and his other half returned to Las Vegas to visit the victims of the incident. "You have helped us try to begin the healing process by seeing the strength each one of you have," Brittany Aldean wrote in an Instagram post.

Updates on the investigation of Vegas shooting

Meanwhile, authorities have finally released the autopsy results of Stephen Craig Paddock two weeks after the attack. Results proved that the suspect had no abnormalities on the brain when he committed the act.

Investigators are still waiting for the results of a toxicology report on the gunman to find out if he was under the influence of drugs or alcohol during the incident.
