Watch: 10-year-old crushes Spiritbox’s Holy Roller on America’s Got Talent

Just over a year ago, we reported on awesome youngster Harper covering Spiritbox’s mega-single Holy Roller, gaining attention from the band themselves plus all sorts of appreciators on the internet. Now, that very singer – who is only 10 years old! – headed to America’s Got Talent…

Harper, who travelled all the way from Somerset in England with her dad, hit the stage to surprise the America’s Got Talent judges sat before her. "She looks like a princess, but sings like a heavy metal warrior!," reads a description in the AGT clip. "Harper performs Holy Roller by Spiritbox and shocks the judges with her surprising voice."

Simon Cowell himself even calls the whole thing "brilliant", while her dad proudly watches on and enthuses, "I love it!"

Amazing. Check it out now:

Last night (June 14), Harper also joined Spiritbox onstage in London to perform the song live with the band.

YES!
