Taylor Swift

Friday-next Sunday: We know America's hottest pop star is going to stage quite a spectacle, with emphasis on material from her current blockbuster album, "1989." What we don't know: Who will her special guests in St. Paul be? On this tour, she's had everybody from Lorde and Little Big Town to Jason Derulo and Nick Jonas. Some guests have been singers, but the U.S. women's soccer team, Julia Roberts and Heidi Klum came onstage just to strut their stuff. So we will hear "Shake It Off," "Blank Space" and an oldie or two such as "Love Story." But what else? Australian singer-songwriter Vance Joy opens. (7:30 p.m. Sept. 11-13. $39.50-$139.50. Xcel Energy Center, W. 7th St. and Kellogg Blvd., St. Paul. ticketmaster.com.)
