UNTOLD ONE 2026 welcomed more than 500,000 festivalgoers to Cluj-Napoca, and narrowing the lineup down to five sets was no easy task.

There are festivals that put together a great lineup, festivals that build impressive stages, and festivals that become destinations in themselves. UNTOLD ONE 2026 managed to be all three. Earlier this August, our team went to Cluj-Napoca from August 6–9 for UNTOLD festival. More than 200 artists performed across the festival, with the event ultimately welcoming more than 500,000 festivalgoers over four days and four nights. But attendance figures only tell part of the story.

What made UNTOLD ONE particularly interesting was the way it continued to push beyond the conventional definition of an EDM festival. The Mainstage delivered the global superstars and enormous singalong moments expected from a festival of this scale, while Galaxy and the other stages offered everything from underground techno to melodic house, urban music and drum & bass. The tram stage provided up and coming artists to showcase their talent while the alchemy stage had some of the biggest hip hop acts of Romania and the world performing there. The result was a festival that could feel completely different depending on where you stood.

With so many incredible performances across the weekend, narrowing the lineup down to just five was an extremely difficult task. When names like Carl Cox, Solomun, Sara Landry and Swae Lee don’t even make the final cut, you know UNTOLD ONE delivered a weekend packed with exceptional music and unforgettable memories.

After four days of music, these are our top five acts from UNTOLD ONE 2026.

5.Flo Rida

Sometimes a festival set doesn’t need to be complicated, It just needs to be fun and Flo Rida delivered exactly that. Performing at the Mainstage with a catalogue packed with instantly recognizable and nostalgic hits, Flo Rida turned UNTOLD into one enormous party. Tracks like “Low,” “Whistle” and “GDFR” provided the kind of universal crowd reaction that few artists can replicate. In my personal opinion, the crowd was the loudest during his set

His performance also brought a completely different energy to the closing night. After four days of EDM, techno, house and live performances, Flo Rida’s combination of hip-hop, pop and dancefloor anthems felt like the perfect way to celebrate the end of the festival.

It was nostalgic, energetic and incredibly entertaining.

4.Lost Frequencies

Lost Frequencies delivered one of the weekend’s most versatile sets, combining his melodic house sound with the kind of accessible festival energy that has made him a global name.

His performance was filled with familiar records, emotional melodies and moments designed perfectly for a crowd of tens of thousands.

One of the highlights came when Loredana Groza joined him on stage for their collaboration, bringing an unmistakably Romanian element to an otherwise international festival programme.

That moment summed up what UNTOLD does particularly well: bringing global electronic music together with the local culture and identity of Romania.

Lost Frequencies also demonstrated that you don’t necessarily need the hardest drops or most aggressive production to command a festival crowd.

Melodic, emotional and perfectly suited to the UNTOLD atmosphere.

3.Sebastian Ingrosso

Few artists understand the DNA of a festival quite like Sebastian Ingrosso.

With decades of experience performing on some of the world’s biggest stages, Ingrosso knows exactly how to build anticipation, when to release the energy and, most importantly, which records can turn a massive crowd into one voice.

His UNTOLD set delivered that familiar combination of progressive melodies, huge festival moments and Swedish House Mafia nostalgia, while still feeling relevant to a modern festival audience.

There is something particularly satisfying about listening to whole crowd singing along to “Dont you worry child”, It is one of those festival moments that words cannot really describe. You simply have to be there.

2.The Chainsmokers

It feels unfair to pick top five when there were so many artists pouring their heart out in their performances, one of them was the returning duo of the Chainsmokers, who played their ever green hits such as Dont let me down, Closer and Something just like this but also sharing a tribute to their late friend Juice wrld with “Sugarfish” and their emotional performance of the unreleased ID “Used to call”.

The Chainsmokers have always had a special relationship with festival crowds, and their UNTOLD return showed exactly why. Their set managed to balance nostalgia with the energy of a modern festival performance, taking the audience through some of the biggest records of their career while still keeping the show feeling fresh.

1. MEDUZA³ LIVE

MEDUZA have become synonymous with some of the biggest house records of the past several years, but MEDUZA³ LIVE took the Italian trio’s sound into a different dimension.

Rather than simply delivering another DJ set, the live concept gave their music a larger, more immersive presentation. Their biggest records such as “Bad memories”, “Piece of your heart” and “Paradise” sounded particularly powerful in the UNTOLD environment, with the combination of live elements, vocals and festival-scale production creating a show that felt closer to a concert than a conventional club set.

It was also one of the weekend’s strongest examples of how electronic music continues to evolve, A polished, energetic and genuinely impressive live electronic performance.

UNTOLD ONE 2026 was a reminder of why the festival has become one of Europe’s most important electronic-music destinations.

It wasn’t simply about having the biggest names on the poster. It was about creating a festival where Lewis Capaldi could deliver an emotional singalong, MEDUZA³ could transform a DJ show into a hybrid live spectacle, Kygo could bring his tropical house vibes to a stadium crowd and R3JACK (Afrojack & R3HAB) could turn the mainstage in a dance floor.

And somewhere else on the festival grounds, Carl Cox, Solomun, Sara Landry, Denzel Curry and hundreds of other artists were creating their own unforgettable moments.
