Connor Closs gave The Voice viewers a beautiful dose of Y2K nostalgia with a performance that was as romantic as it was vocally impressive. Taking on NSYNC’s beloved ballad This I Promise You, the Team Adam singer turned the stage into an intimate moment, dedicating the song to his newly engaged fiancée, Sarah.

The performance took place during the first night of the Season 30 Live Shows on November 9, 2026. Rather than choosing an upbeat pop hit for Y2K Night, Connor went with one of the era’s most enduring love songs, allowing its heartfelt lyrics and sweeping melody to showcase his vocal strengths.

Connor handled the emotional ballad with remarkable control, moving effortlessly between tender passages, intricate vocal runs and soaring high notes. His rich tone and expressive falsetto brought a fresh sense of emotion to the familiar song, making the performance feel personal rather than simply nostalgic.

Adam Levine was clearly impressed, praising Connor as one of the competition’s strongest singers. The coach particularly highlighted his beautiful, rich vocal tone across every register, noting that Connor does not need to rely on shouting or excessive theatrics to stand out.

The performance proved to be a winning moment for Connor, who earned America’s vote and secured his place in the Top 10. By combining a meaningful dedication with an impressive vocal showcase, he reminded viewers why he has become one of Team Adam’s standout contestants.
