Scott and his partner Kylie Jenner, who was in attendance at the Houston show, have stated in separate social media posts that they are devastated by the tragedy.
Jenner said both she and Scott didn’t know what was happening in the crowd at the time.
Similar situations have erupted at concerts in the past – here’s how artists have asked crowds to stay safe.
“We got to look out for safety first, for real. Nobody gets hurt. That’s number one,” said Mike Shinoda in the video.
“Pick them up,” the crowd yelled back.
“Hold on one second,” Grohl said, pausing and pointing at someone in the crowd. “Does that kid need somewhere to sit?”
Grohl then invited the child and his parents to sit at the edge of the stage.
In 2018, metal band Slayer were opening their final tour in San Diego, California, when the concert was paused due to the size of the crowd. Audience members were instructed to clear the aisles for safety reasons.
“We live in a society of rules. But these rules are for your safety,” he told the crowd. “They need to have cleared aisles so when something does happen, everybody has an exit, okay.”
The show eventually continued.
“Everybody back up, look. Watch out,” he begins. “Pick the girls up, bro. Pick the girls up !!! Pick the f *** ing girls up, what’s wrong with y’all.”
The rapper continued yelling at the crowd to “back up” and “calm down” before he began performing again.
“They telling me it’s a lot of people passing out. They keep stopping my music because people are passing out. I care about you guys’ safety first,” he said, as organizers continued to give him more information. “Everybody take three steps back and we can start the music right away.”
Some social media users drew comparisons to Carti’s set, saying that the organizers at Astroworld should have forced a stop like they did at Lollapalooza.
“If you guys do not follow the rules, if you guys jump over to the floor, if you guys do anything that they consider dangerous, not one, not two, but just one person messing up, this show is over,” the loudspeaker announcement said before Carti’s appearance. “We are fighting, we are convincing them to let us do this show for you, but this show now, if it happens, it is on you. So please, let’s have a good time and be respectful.”
