When McDonald’s Slovenija launched its McShaker line in April 2026, the campaign led with a song rather than a product shot. Tresi, tresi (“shake, shake”) is an original track written for the launch by agency Futura DDB and produced by Bright, pairing the accordion of folk ensemble Firbci with electronic producer REDHEDII, released as a music video and extended into a mobile game in which players shake their phone. Within two weeks the video passed 537,000 views on YouTube and briefly topped the Slovenian YouTube chart as the most-watched video in the country. Cycle Studio Zagreb synced the music and voice-over to picture and mixed the three delivered versions — the music video and the two product cutdowns. Released 21 April 2026.
“Fries + spice = new banger track! Firbci x REDHEDII cooked up something loud and we filmed it. New McD’s drop hits … this one stays on repeat.” — Bright, on Tresi, tresi
“The accordion of the band Firbci and the electronic rhythms of producer REDHEDII merged into a track that within two weeks of release passed 537,000 views on YouTube and briefly climbed to the top of the Slovenian chart.” — Eva Peserl, Marketing Magazin
