I lover her life performances...I am so mad that it is impossible to find her live performance of Save My Soul from the Late Night Show. NBC deleted it.. ugh...
She's very technical, high notes and different vowels require appropriate jaw movements to produce the acoustical space necessary for a resonant note to occur. So, her ear piece naturally gonna be a little all over the place. She still hit some impressive notes without the piece, which to me is absolutely insane and only enforces her mastery over the vocals, she is really something else 🙌
