Rapper Travis Scott will give full refunds to all attendees who bought tickets to Astroworld, a music festival on Friday that ended in tragedy. He will also not perform at the Day N Vegas Festival on Saturday in Las Vegas.

Sources told Variety that Scott was “too distraught to play." After a crowd crush, eight people died and about 300 were injured. The ages of the eight people who died ranged from 14 to 27.

Police are investigating claims that a security officer was injected in the neck with a drug.

A criminal investigation has been called for by Houston Police.

General admission for a two-day pass to Astroworld in 2021 cost concert-goers around $300 plus $65 in fees, VIP passes cost $725 plus $69 in fees, and the “No Bystander VIP ticket” cost $1,000 with $78 in fees. The Houston festival had 50,000 attendees in total. The second day of the event was canceled.

Rapper Roddy Ricch, who took the stage before Scott, has pledged to give his entire earnings from festivals in 2021 to the families of the eight who died.

“Please have the families of those who we lost yesterday reach out,” Ricch wrote on his Instagram story on Saturday. “I’ll be donating my net compensation to the families of this incident. #Pray4Houston.”

Scott was the top-billed performer at Day N Vegas on Saturday. The festival has not announced who will be the headliner. Rapper Kendrick Lamar is the headliner on Friday and rapper Tyler the Creator is the headliner on Sunday.
