A fatal crowd surge during a performance by US rapper Travis Scott on Friday night has become one of the deadliest live music incidents in recent years. Crowd crushes during the Houston show, which was part of the Astroworld Music Festival, led to eight deaths and dozens of injuries.

The incident is still being investigated, with criminal investigations also underway. How does such catastrophe emerge in a space where people are supposed to be enjoying themselves?

"Stop the show" and the staff did nothing. This shit is fucking heartbreaking #AstroWorld vc:@JanthonyOlivera pic.twitter.com/5vVZKLKV7h
