Pentatonix brought a wave of pure nostalgia and high-energy vocal mastery to the Great Allentown Fair on August 31, 2024, delivering a “90s Dance Medley” that had the crowd on its feet from the very first beat. Known for their signature a cappella precision, the Grammy-winning group transformed iconic club classics into a seamless, electrifying live experience powered entirely by the human voice.

The medley stitched together some of the most recognizable dance hits of the decade, including “Be My Lover” by La Bouche, “What Is Love” by Haddaway, “Better Off Alone” by Alice Deejay, “Rhythm Is a Dancer” by Snap!, and Eiffel 65’s “Blue (Da Ba Dee),” among others. Each transition was executed with near-mechanical precision, yet carried the raw energy of a live concert designed to move an entire generation.

Mitch Grassi stood out with his soaring vocal lines, cutting through the arrangement with bright, unmistakable clarity, while Kirstin Maldonado anchored the performance with smooth, emotive leads that balanced the intensity of the medley. Scott Hoying and Matt Sallee filled out the harmonies with rich, layered depth, creating a wall of sound that replaced what would normally be synths and instruments in a traditional dance set.

At the heart of the rhythm, Kevin Olusola’s beatboxing served as the engine of the performance, recreating pounding club beats and driving the momentum forward with relentless energy. His vocal percussion gave the medley its pulse, making the entire arrangement feel less like a cover performance and more like a full-scale dance production built from scratch.

What made the moment stand out was not just the technical brilliance, but the way Pentatonix captured the spirit of the 90s dance era — euphoric, nostalgic, and unapologetically fun. The audience responded instantly, with many singing along, dancing, and reacting as each familiar hook dropped into the next.

Beyond the medley itself, the 2024 Great Allentown Fair performance also highlighted the group’s broader live show format, which included viral collaborations such as Scott Hoying’s duet with David Archuleta, a massive Taylor Swift evolution medley, and a finale featuring Queen’s “Bohemian Rhapsody,” followed by emotional encore performances of “Can’t Help Falling in Love” and “Hallelujah.”

But it was the 90s Dance Medley that stole the night — a high-voltage reminder of why Pentatonix continues to dominate the a cappella world. By turning nostalgia into a living, breathing performance, they didn’t just revisit the past… they made it dance again.
