Cheez-It ages real cheese to hip-hop, then sells the snack as a music drop
A Swiss study said hip-hop changes aging cheese, so Cheez-It played music to 1,000-pound barrels for six months and launched the result as a mixtape.

What it had to solve
Cheez-It snacks are made with real aged cheese, but that was an invisible fact competing with louder snack marketing. When Leo Burnett heard about a Swiss study suggesting cheese aged to hip-hop tasted noticeably different, the agency saw a way to make the real-cheese claim physical and entertaining.
How it works
Cheez-It's snacks depend on real aged cheese, but 'real cheese' is a claim any cracker brand can make and few consumers can verify. The brand's agencies instead found proof in an obscure Swiss experiment suggesting that cheese aged to hip-hop developed a noticeably different aroma and flavor — an invitation to change the product, not just the message.
Leo Burnett, Pandora and Studio Resonate selected a hip-hop playlist built to mirror that study's tempo and timbre, strapped transducers to four 1,000-pound barrels of aging cheese at a facility in Idaho, and let the music vibrate through them 24 hours a day for six months. In a blind panel test against cheese aged in silence, the sonically aged batch came out distinctly milder in flavor and aroma with a different texture and finish.
Kellogg's used the experimental cheese to make limited 'Aged by Audio' Cheez-It boxes, sold on a dedicated microsite where each pack linked to a consumer mixtape of the aging playlist, with rapper and radio host Sway Calloway supporting the launch. The boxes sold out in 12 days, web traffic tripled, engagement with the real-cheese message quadrupled, and collectors resold empties for around $150 — proof that a product experiment could outperform a product claim.
Why it lands
- The campaign made an invisible quality claim — real cheese — into something people could taste, hear and collect.
- Music did real work in the factory, so the marketing story was also the manufacturing story and could not be faked.
- Launching the snack as a music drop turned a limited-edition product into culture instead of a press release.
- The six-month experiment created a physical artifact whose scarcity, not the ad budget, drove demand.
What it did
The boxes sold out in 12 days, web traffic tripled, and engagement with the real-cheese message quadrupled, while empty boxes began reselling for around $150 online. The work won a Gold Effie in the United States in 2023 and was named the 2024 Global Grand Effie winner in the Digital category.
What you can take
When the product truth is invisible, don't claim it louder — make the production process itself the proof, and let the product carry the story.
Since then
Aged by Audio became one of the most awarded food campaigns of its cycle: a Gold Effie in the United States in 2023, then the 2024 Global Grand Effie in the Digital category, selected among national winners from around the world. The campaign gave Cheez-It a template for proving its real-cheese positioning through stunts rather than claims, and WARC catalogued it in its case library and Effective 100 rankings. The sold-out boxes also turned into collector items, keeping the story alive long after the run ended.
