Concert venues in the Bay Area and around the world have long taken measures to help provide safe environments for live music. But sadly, concert safety is once again a topic of discussion in the aftermath of the Nov. 5 tragedy at the Astroworld festival.

In that Houston concert, what has been identified as a massive crowd-surge incident unfolded while headliner Travis Scott was performing, leading to nine deaths and hundreds of injuries. While local event organizers say too much remains unknown to ascertain the lessons of Astroworld, the potential dangers of large crowds in small spaces are on the mind of entertainment officials and concertgoers everywhere.
