Austin Monthly Magazine on Instagram: "Pop star Sabrina Carpenter brought out country legends The Chicks to perform two songs during her headlining set at ACL Fest on Saturday night. The group performed their song “Wide Open Spaces” and stayed onstage to joint Carpenter for her hit “Please Please Please.” The impromptu performance marked the second time in as many weekends that Carpenter brought a country star onstage, as Shania Twain made a guest appearance last weekend."
