3/31/23: Auditorium roof collapses during storm at Morbid Angel concert

I know that Morbid Angel and R.E.M. are not the same genre of music (understatement) but things like this are the reason why shows are cancelled or rescheduled in bad weather. Information is very sketchy, but First Responders were told to send 20 ambulances to start.

Belvidere is in northern Illinois, between Rockford and Chicago.
