 Hell, before last night, I had never heard of an Ingrid Andrus. And I understand the stadiums can be tough. I understand that there are some venues that are really, really tricky. There is feedback, and it can be difficult. I understand that. However, this is a professional singer. This is what she does for a living. I'm just trying to figure out how that could go that badly, how you can tank that that badly. Maybe it's not your best night, but how can it be your worst night?
