Let me spill the real.., when it comes to Mariah, any lamb worth his/her salt knows while her voice is still impressive, for it to sound it's best these days i.e. Flexibility, dexterity, run/riffs and power, Mariah needs sleep, no alcohol, vocal rest and humidifiers. Sooo it stands to reason that she'all continue to convince the world her voice is shot if she keeps turning up to these major billings without the necessary vocal preparation. Set, dancers and outfit on point but again, the mime track is doing all the heavy lifting because other things have taken priority once again.
