But Swift has also made each show a news event by adding two “surprise songs,” often with headline-grabbing guests. Music critics have portrayed the Eras Tour as showing Swift at the top of her game as a media-savvy, big-tent talent, a pop star with a knack for grand spectacle as well as the polished artistry of a classic songwriter. Shania Twain, the country-pop star whose career in some ways prefigured Swift’s, caught the Las Vegas stop of the Eras Tour, a 44-plus song production that goes as long as three and a half hours. She praised Swift’s “beautiful balance” of high-tech stagecraft and intimate performance segments. (Swift’s representatives declined to comment for this article.)
