ULTRA Europe 2025 returned bigger, louder, and more unforgettable than ever, cementing its place as one of the most powerful global festivals in the electronic music world. Over 150,000 fans from more than 100 countries gathered at Park Mladeži in Split for three days of jaw-dropping production, nonstop energy, and world-class performances but one moment in particular stood out.
Swedish hitmaker Alesso delivered a massive Friday night Main Stage set, which reached a fever pitch when he brought out surprise guest Martin Garrix. The crowd erupted as the two superstar DJs launched into the live debut of their highly-anticipated collaboration, “Inside Our Hearts.” The emotional, high-energy anthem, officially out July 25 via STMPD RCRDS, marks their first-ever official collaboration, and its premiere at ULTRA Europe was nothing short of historic.
“We’ve been working on this song for two years,” Alesso told the crowd before the drop, “and we think we finally finished it!”
From that moment on, the Main Stage turned into a wave of unity and emotion. Fans lit up the night sky with flares, flags, and phones, singing along to the uplifting lyrics that had already become iconic after being teased at Garrix’s 2023 ULTRA Miami set. The duo followed up the debut with a seismic string of mashups, including “Reload” by Sebastian Ingrosso & Tommy Trash, a fusion of “Scared To Be Lonely” and “Calling (Lose My Mind),” and crowd-favorite edits that kept the energy peaking.
ULTRA Europe 2025 welcomed its largest crowd to date, with over 150,000 attendees packing the festival site over the weekend. Featuring performances from industry giants including Hardwell, Afrojack, and more, the event showcased the best of techno, house, and mainstage EDM. Every corner of the globe was represented, creating a truly international celebration of dance music culture.
Fans who couldn’t attend in person tuned in by the millions via #ULTRALIVE on UMF TV, which broadcast the festival in real-time with cinematic production quality and drone-shot stage views that made the experience feel larger than life.
RESISTANCE Stage A Landmark for Dance Music
Alongside the festival’s electrifying Main Stage, ULTRA Europe 2025 dedicated a powerful platform to underground music with its iconic RESISTANCE Stage at Park Mladeži. True to its reputation, this stage delivered some of the most immersive techno and deep-house experiences of the weekend. Highlights included legendary sets from innovators like Carl Cox, Solomun, Amelie Lens, ARTBAT, and Adam Beyer b2b Mau P, a back-to-back debut that had fans buzzing.
Adding fresh energy, the lineup featured emerging talents such as Korolova, Mind Against, Brina Knauss, Johannes Brecht, Ginchy, and Croatia’s own Insolate, plus the intriguing Shipe B2B Jock set and pioneer Tomo in der Mühlen. With its underground vibe, club-style production, and a mix of global stars and regional pros, the RESISTANCE Stage stood out as a highlight for fans craving depth, rhythmic intensity, and raw dancefloor energy.
