Mariah Carey was disconbobulated due to a lack of coordination between her head/ear piece and the vocal overdub. It was a disaster according to the artist. So glad I a, 60+ and experienced live music for minimal cost. (Not to fault overpriced shows lypsynching). To each their own. Had she been doing it gratis I get it but I bet she got some dinero for just showing up, Don't wish to argue how professional musicians perform and changes over the year but just shaking my head How disappointed she could be.
