The ease
The vibrato
Sara did it y'all. She delivered easily one of the best vocals of the year.
Sara seemed to be struggling with her upper register the past year, not getting the raw power on the high notes on Brave live like she did in studio. Those were D5's. In this performance she delivered flawlessly executed Db5's, incredibly vibratory Eb5's and two full voice F5's. And, unlike Sia, she did it without cracking like a pane of glass being shot by a missile. Sara is on track to become an unstoppable vocal monster. Keep up the good work Sara.
