According to an online search, death metal bands were booked to play the venue Friday night. The bands were: Revocation, Morbid Angel, and Skeletal Remains.

Morbid Angel put out a statement, saying in part: "Tonights show is Canceled due to a Tornado that hit the Venue…We are currently sheltering in place, and want to extend our support and hope that everyone at the show tonight is safe."

A band was reportedly playing on stage at the time of the collapse. The venue is the type of scene where a crowd would be standing in front of the stage as the show was performed. Video shows the roof directly above the standing area collapsed.
