Best Distraction: Sia's Dancers
On Sunday, Sia spent her entire set nearly motionless, belting out lyrics while standing in place like a potted plant. She likes it that way, and has a full cast of dancers and actors to play out the ideas and emotions live onstage and/or in pre-recorded pieces shot for the big screens. First among them remains Maddie Ziegler, the young dancer who stars in several Sia music videos, and who exploded in frantic spasms of emotion. She bent her limbs, twisted her face, fishhooked her mouth, crawled the floor, battled with other dancers, writhed and hopped in the spirit of the open nerves being exposed in the songs "Alive" and "Big Girls Cry."
