I love the way she communicates with her audio operators where she incorporates it to her choreography.. Notice at 3:48 she was asking to raise the volume of her in ear.. Its so subtle you could barely notice it in the crowd..
You could tell she was having so MUCH FUN and living this performance up, her little cheeky dance moves and bopping, how shes vibing off her dancers, the way she threw in that extra long high note as the last note at the very end and the little satisfied smile she has. This is what she lives for, she was feeling. Truly born for the stage and enjoying herself I mean for example just look at 3.12 - 3.30 that's just pure joy and having fun! Sometimes when I need a cheer up good vibe I put this on and try and get into this mood of just bopping to her voice, gotta love her!
I love how confident christina is…in the sense, she isn’t afraid or so self absorbed to have female dancers. When you see other performers they only want male dancers.
