Spiritbox's 2020 single "Holy Roller" is arguably their heaviest song. The Canadian trio fronted by Courtney LaPlante seem to have found a sweet-spot between djenty riffs and swooning clean vocals, but "Holy Roller" is a monstrous metalcore banger with ferocious screams, which makes it all the more surprising to hear a 9-year-old girl absolutely nail it.
On Wednesday, a young musician named Harper uploaded her very first video to YouTube, and it's a professionally-recorded cover of the Spiritbox heater. Unlike what you would expect from a child singer whose voice isn't close to being fully developed, Harper legitimately nails LaPlante's ferocious range and brings the power of a vocalist twice her size and with many more years of experience.
"Harper wanted to cover Spiritbox, and it sounded so sick, so we also did a little video," reads the video's description. "No vocal help from me at all!"
It's incredibly impressive. Check it out above via YouTube.
