I agree — it was a mesmerizing performance. Yes, the mop head hair, and giant bows were affectations — but, so what? Most performers wear some sort of costume on stage. The stagecraft was brilliant too. I should add that I seldom tune into music made after about 1980; so, I am definitely not part of Sia’s fan demographic. If she weren’t part of Trump Night Live, I probably would never have watched or heard her. The performance was a surprise extra bonus for tuning into Trump.
There was a 'surprise extra bonus' for attendees at Ford Theater who wanted to be there with the President that unfortunate evening.
