It was my understanding that she was performing a few throwback hits from her first album to celebrate its 25th year (like Essence). So if that's the case, then it's not that big of a deal. Also, she was going to be first or second, and honestly, people don't show up to Essence til late
The crowd doesn't get packed until maybe an hour and a half after start time. She wasn't a main act. She will recover from this.
