In the world of music, there are “covers,” and then there are “reclamations.” When Kelly Clarkson stepped into the SiriusXM studios for a live session, no one expected that a casual radio appearance would result in one of the most talked-about vocal performances of the decade. Covering Sia’s “Chandelier”—a song notorious for its grueling range and raw emotional desperation—Clarkson didn’t just hit the notes; she “possessed” them. The atmosphere in the recording booth shifted the moment the piano melody began. Known for her crystalline pop-rock tone, Kelly tapped into a darker, grittier texture that few had heard from her before, leaving witnesses in the booth reportedly frozen as she unleashed a vocal power that felt less like a performance and more like a visceral emotional release. The Transformation in the Booth As she reached the iconic chorus, Clarkson didn’t shy away from the vocal breaks and raspy growls that make Sia’s original so haunting. “It wasn’t just singing; it was a total possession!” one observer remarked, describing the way Kelly seemed to physically transform as she channeled the song’s themes of escapism and pain. This wasn’t merely a technical exercise for the American Idol alumna; it was a moment of complete artistic immersion. Her ability to mimic the “guttural” essence of the original while maintaining her own soulful resonance created a hauntingly unique soundscape that captivated everyone present. Technical Mastery Meets Raw Emotion What makes this specific cover a classic highlight in the “Kellyoke” era is the staggering level of technical difficulty she conquered. Kelly utilized a controlled vocal fry and grit on the high notes, mimicking Sia’s signature style while maintaining her own signature power. She reached the climax of the song—the massive $Eb5$ and $F5$ notes—with a clarity and strength that reminded the industry why she remains a vocal titan. By adding her own bluesy runs, she effectively turned a synth-pop ballad into a soul-shattering anthem. The performance proved that she is a “vocal chameleon” capable of standing toe-to-toe with the most challenging compositions in modern music history. A Viral Phenomenon and the Kellyoke Legacy Since the video of the session was released, it has become a staple in vocal analysis videos across YouTube and TikTok. Fans and vocal coaches alike point to this performance as the gold standard for how to cover a difficult song: by respecting the original artist’s DNA while injecting one’s own undeniable spirit. This performance of “Chandelier” arguably paved the way for the popular “Kellyoke” segment on The Kelly Clarkson Show, where she continues to go viral on a weekly basis. It serves as a powerful reminder that whether she is tackling Whitney Houston, Sia, or Aretha Franklin, Kelly Clarkson doesn’t just sing a song—she lives in it. By late 2025, the cover remains one of the most-watched clips in the SiriusXM archive, a testament to a voice that can still stop the world in its tracks.
