So, how does it feel to perform with Spiritbox? “I definitely felt like I had more energy up there than on America’s Got Talent,” remembers Harper. “On America’s Got Talent, I was just standing there shaking.” Before AGT, she hadn’t been on the stage a great deal, and she was so nervous in the run-up to her performance that her audition had to be pushed back. Having Courtney by her side proved to be helpful, as did a different sort of audience than the spectators who watched her audition with looks of confusion. “When I was with Courtney, I swear she gave me her energy and all the people in the crowd, since they knew metal music, [I felt like] they would understand it,” she continues. “When I got onstage, I was like, ‘I love this. I wanna go again!’ My heart was beating so much after that. It was so fun, but also scary.”
After her audition video went viral, everyone at Harper’s school seemed to now know who she was. They’d all seen the clip, and they kept asking her how she managed to sound like she did. Being recognised has become a steadily more regular occurrence – she’s even encountered people in her local Costa asking, “Are you Harper off America’s Got Talent?” Naturally, it’s a lot to take in. “I still haven’t got used to it,” she says. “It’s still quite annoying [when it comes from] teenagers.”
