I saw Mariah on her “Caution” tour and she was outstanding. I’m 100% not kidding. She sang live and there were times she sounded just like she did in 1990. The reason this does not often translate to these “one off” performances is nerves. It’s one thing performing for your fans—people who have paid to see you & another to sing for a lot of haters. Vocally, she was off last night, but she is still better vocally than anyone else in the game.
