Five months into Taylor Swift’s wildly successful Eras Tour, after she’d brought the tour across the United States and to Mexico, she took the epic concert experience to Buenos Aires, Argentina, where she switched up one of the most anticipated parts of her shows. Instead of singing two surprise songs that aren’t on the three-and-a-half-hour-long show’s expansive setlist toward the end of the performance, she began doing mashups of those surprise songs. [time-brightcove not-tgx=”true”] The first time around, she combined two 1989 (Taylor’s Version) songs: “Is It Over Now?” and “Out of the Woods.” Following a perhaps unsurprisingly positive reception, the singer has continued to do mashups while touring throughout Brazil, Japan, Australia, and Singapore.
