Travis Scott, Drake, Live Nation, others sued by concertgoers over crowd surge at Astroworld music festival

At least three lawsuits have been filed on behalf of people who say they were injured at the Houston music festival where at least eight people were killed. The defendants include rappers Travis Scott and Drake and venue and entertainment company Live Nation. Two of the suits are seeking $1 million in damages.

A crowd surge occurred during Scott's performance on Friday night, when concertgoers started to "compress" toward the stage, Houston Fire Chief Samuel Peña said early Saturday. 

"That caused some panic, and it started causing some injuries," Peña said. At least eight people, including two teenagers, were killed and dozens were hospitalized.
