NRG Park, owned and managed by the Harris County Sports & Convention Corporation (HCSCC), also had expanded upon the previous year's setup by two new gates and expanded room for crowd traffic flow around the 'Yellow Lot' parking area on which the festival was held, one of a series of them that surround NRG Arena, according to Miller on November 17. Inquiries to verify those numbers from the Houston Chronicle as of December 3 were declined. The city of Houston and Harris County organized security for the event, with both mayor Sylvester Turner and General Manager for NRG Park Mark Miller claiming more than 1,000 security staff and police were present, more than double the total from the prior Astroworld concert, with the city specifically providing more security for the festival than it had for the 2021 World Series, which had ended in Houston three days earlier. Authorities initially planned to limit attendees to 70,000 the first night, and that was reduced to 50,000 closer to the event, even though city fire codes permitted 200,000 people. Tickets were sold out in under an hour upon going on sale in May, and 100,000 in total were expected to attend. The 2021 festival was planned for two consecutive nights. Apple Music streamed Scott's performance live. The event was organized and managed by Live Nation and its affiliates. The Astroworld Festival is an annual music event founded by American rapper Travis Scott in 2018, taking its name from his third studio album released the same year.

Multiple concertgoers documented the incident, posting videos and recounting their experiences on social media. Twenty-five people were hospitalized, and more than 300 people were treated for injuries at the festival's field hospital. The cause of death for all ten was ruled to be accidental compressive asphyxiation, with one of the ten affected by the additional influence of a toxic combination of drugs and alcohol. Eight people died on the night of the concert, and two more died in the hospital over the following days. On November 5, 2021, a fatal crowd crush occurred during the first night of the 2021 Astroworld Festival, a music event founded by American rapper Travis Scott that was held at NRG Park in Houston, Texas.
