After playing a few tracks from her 1989 era live, the pop star approached the centre of the stage with an acoustic guitar in hand and suggested to the audience that she'd been working on something big.
"Instead of telling you about it, we'll just show you," she told the crowd as the screen illuminated behind her.
"1989 (Taylor's Version) available October 27th!" she cheered.
Across three-and-a-half hours, the pop superstar offered fans a bevy of career-spanning hits that was less of a greatest hits collection, and more of a live celebration of a veteran artist.
Throughout the dozen tracks, it was as if the ground shook with the rapturous sound of 70,000 fans scream-singing along.Â
This is Swift's house - filled with fans in light Taylor Swift cosplay (pink dresses for her 2019 album Lover, black leather and snakeskin prints for 2017's Reputation, sequins and A-line skirts for 2014's 1989, and so on).
In a summer stacked with superstar tours celebrating giant new releases - including the larger-than-life experiences of Beyonce's Renaissance World Tour and Drake's 56-date It Was All a Blur Tour - Swift's Eras Tour stands proudly among them.
Swift will bring her Eras Tour to Australia in February.
