There is a specific kind of magic that settles over the city of Cluj-Napoca every summer, but the buzz surrounding UNTOLD 2026 feels different. Having just wrapped up a monumental decade of dance, the festival is officially entering its next chapter, appropriately titled UNTOLD ONE. The first wave of artists has just been unleashed, and if the initial line-up is anything to go by, Romania is about to host the most ambitious electronic and pop spectacle the European continent has seen in years.
Taking over the iconic Cluj Arena from the 6th to the 9th of August, the 2026 edition is leaning heavily into its reputation as a global hub for hitmakers. Leading the charge is the tropical house pioneer KYGO, whose return to Transylvania is already being hailed as a headline set for the ages. Known for his sun-drenched melodies and record-breaking streaming numbers, KYGO has a unique ability to turn a stadium into an intimate, emotive experience. Joining him at the top of the bill are the Grammy Award-winning duo THE CHAINSMOKERS, who are making their highly anticipated return to the UNTOLD mainstage. Since their last appearance in 2018, the duo has shifted the boundaries between indie-pop and big-room EDM, and their set is expected to be a non-stop singalong of global anthems like “Closer” and “Something Just Like This.”
The festival has always been a broad church for electronic music fans, and the inclusion of SEBASTIAN INGROSSO ensures that the “Swedish House” energy remains firmly intact. As a titan of the progressive house world, SEBASTIAN INGROSSO brings a level of prestige and high-octane production that is perfectly suited for the legendary UNTOLD mainstage visuals. Adding to the sheer star power of the weekend is the helmet-clad phenomenon MARSHMELLO, whose cross-genre appeal is set to draw one of the largest crowds of the weekend. Whether it’s his viral pop collaborations or his heavier dubstep-leaning tracks, MARSHMELLO is a master of the festival format.
In a move that will delight fans of the high-energy “Cake Me” culture, the legendary STEVE AOKI is also confirmed to return. His sets are more than just musical performances; they are chaotic, immersive experiences that have become a staple of the UNTOLD identity. We are also seeing a massive back-to-back performance that has sent the forums into a frenzy: AFROJACK B2B R3HAB. These two Dutch heavyweights sharing the decks is a rare treat and promises a masterclass in high-velocity festival house. Rounding out the electronic heavy-hitters is LOST FREQUENCIES, the Belgian maestro of melodic house, whose track record of chart-topping hits like “Are You With Me” makes him an essential addition to any world-class roster.
While the DJs often grab the headlines, UNTOLD ONE is making a significant push into the world of live urban and pop music. In a massive scoop for the festival, the legendary FLO RIDA will be taking to the mainstage for the very first time. With over 80 million records sold, his set will undoubtedly be a high-energy journey through some of the biggest club hits of the last two decades. Joining him is SWAE LEE, one of the most influential voices of the current hip-hop generation. As the voice behind the multi-billion-streamed “Sunflower,” SWAE LEE represents the cutting edge of modern pop and rap, bringing a fresh, melodic energy to the Transylvanian nights.
The diversity of the 2026 line-up is further cemented by the inclusion of TASH SULTANA, the gender-fluid Australian multi-instrumentalist who is set to bring a soulful, psychedelic atmosphere to the festival. Her live-looping mastery is a sight to behold and offers a perfect, organic counterpoint to the synthetic thud of the electronic stages. We also see the inclusion of MËSTIZA, the duo famous for blending traditional flamenco with deep house, ensuring that the festival’s artistic scope remains as wide as ever. And in a last-minute addition that has the “Untolders” community buzzing, the world’s number-one DJ, MARTIN GARRIX, has been confirmed to return with what is being described as a “Special UNTOLD Set,” tailored specifically for the 2026 concept.
With over 200 artists expected to perform across eight distinct stages, this first announcement is merely the tip of the iceberg. From the techno-driven sanctuary of the GALAXY stage to the ethereal vibes of DAYDREAMING, UNTOLD ONE is shaping up to be a total sensory takeover. Organisers are anticipating over 470,000 attendees this year, and with tickets already flying out of the virtual box office, the “World Capital of Night and Magic” is looking more vibrant than ever. If you haven’t secured your pass yet, now would be the time—missing the dawn of the new UNTOLD era simply isn’t an option.
