More eerie details are emerging from fans who attended Travis Scott’s Astrowrold — with many detailing “disturbing” sounds played for the crowd — as police work to determine who is responsible.

Fans have been posting videos on TikTok describing the hours leading up to the stampedes that killed 8 people.

In one clip, the crowd posted by a fan named Mia Moorhead can be seen standing still before Scott took the stage. The DJ was playing loud sounds that were sharp to the ear. A countdown clock was also being shown to the audience.

“As you can see, there was this timer going that was making everyone freak out. And those noises you can hear were going all day long. From 10 AM to the set, these frequency noises with the high bass going all day making people freak out,” the fan explained.
