William Earl Taylor Swift is such a force that her post-quarantine “Eras Tour” was a sensation the moment tickets went on sale. Despite Swift playing the biggest venues possible for multiple days in each city, the wild demand has helped to make each stop national news, especially as they are documented in real time on social media. Livestreams dominate on TikTok, “I-can’t-believe-you-got-tickets” posts rise to the top on Instagram, and the media cycle analyzes every change in Swift’s setlist, as well her famous friends in attendance. Beyond the hoopla, Swift’s May 26 NYC show at MetLife Stadium was a dazzling display of an artist at the height of her powers, able to elevate her success over her previously-set peaks. Swift paved the way to the “Eras Tour” via a wildly productive quarantine, when she recorded her sound-shifting trilogy of albums “Folklore,” “Evermore,” and “Midnights.” Those records broadened her appeal and won new fans, but her audience wondered how she’d ever be able to properly tour that trio plus her previous album, “Lover,” the tour of which was canceled because of COVID-19.
