The doors of the BART open at the Coliseum station. Hundreds of people get off and start to walk in the direction of the twin stadiums in the distance. The typical pre-show excitement from the fans making their way to the venue is palpable. Still, the smell of hot dogs from the vendors in the elevated walkways connecting the venues is a surprise. It’s 8:00 pm on a Saturday, and there is no sporting event scheduled. Rather, the occasion is Sia’s second show of her Nostalgic for the Present Tour in Oakland, California. The venue is the Oracle Arena, the home of the Golden State Warriors. Despite the festive ambience around me, I am only barely able to talk for fear that my voice will betray me; I am overwhelmed. As I enter the Oracle, a 18,000 plus seat arena, I keep thinking that this cannot be the venue where Sia will be playing. But the sights (men, women, girls and boys everywhere are dressed up in wigs, bows, and nude leotards) and sounds (there is already a roaring crowd enjoying the opener Miguel) are real – All these people are here to see Sia.
