Few duos embody the enduring spirit of Tomorrowland like Sunnery James & Ryan Marciano. Since 2011, their performances have threaded energy, heart, and connection across the festival’s largest stages. This year, they doubled down, delivering commanding sets at both the Great Library and Crystal Garden. Their journey into 2025 wasn’t just about music, but about understanding the ways festivals evolve and audiences shift. For Sunnery and Ryan, the stage has always been a mirror, reflecting how deeply dance music can bind people together.
Grounded in the Crowd, Guided by Instinct
At Tomorrowland, the spectacle is overwhelming, from the towering stages to the pyrotechnics. For Sunnery James & Ryan Marciano, the true focus is elsewhere. “We focus on the crowd’s reaction, not just the big jumps or screams but the smaller things. The faces, the way people move, that tells us if we’re in sync. That’s the anchor no matter how big the production gets.” Their approach strips the noise away and locks onto the human element, the most unfiltered measure of whether a set works.
The duo has built their Tomorrowland sets on balance: structure with enough room for instinct. “We prepare most of the structure in advance so it flows, but we never lock it 100%. The energy in the moment can change everything, so we leave space to switch tracks, extend a groove, or build a drop differently if that’s what the crowd needs.” That philosophy means no two weekends are identical. Their Great Library set might have carried a different weight than Crystal Garden, but both relied on responding in real time. It’s a reminder that even the most choreographed stage still breathes with improvisation.
Sunnery James & Ryan Marciano Reveal What Really Happens Beyond the Tomorrowland Stage
Their weekend wasn’t only about lights and music, it was about discipline and pacing. “Usually we’re on site a day before for technical checks and to get a feel for the stage. On the day itself: soundcheck, some time to go through key moments, then we keep it light with clean food, rest, and hydration. The last hour before we play is just about getting into the right headspace together.” That regimen, steady and calm, shows a different side of Tomorrowland. Offstage, their preparation mirrors athletes before competition. Even their snack choice reflects that focus: “Coconut water. Simple, keeps you hydrated, and it works every time.”
Not everything goes according to plan, even on the world’s most polished stage. “A MIDI controller froze for a few seconds during a transition. We worked around it and no one seemed to notice, but in our heads we were already planning the backup move.” The confession pulls back the curtain on what fans rarely see: the constant vigilance required to keep the illusion seamless. For Sunnery and Ryan, the hiccup only reaffirmed their commitment to adaptability, reinforcing that live electronic music carries real stakes.
Amid the countless beats, one stood apart. “Yes. There was a point where the crowd was completely with us on a build, hands in the air, no one on their phone, just locked in. We looked at each other and we didn’t need to say anything.” These rare points of unity are why they continue returning since 2011. Even when storms rolled through, the rain only amplified intensity. “One year the weather turned just before our set and it started to rain. Instead of killing the vibe it made the crowd even wilder. That atmosphere is something we’ll never forget.” These memories anchor their Tomorrowland legacy as much as the stages themselves.
Tomorrowland as a Living Laboratory of House Music
For Sunnery James and Ryan Marciano, Tomorrowland is less about one set than about understanding the shifting fabric of global dance music. “Yes. It’s a global stage with people from everywhere so you want the set to feel like you but also to connect with a very mixed crowd. It forces you to think about the bigger picture.” Backstage, conversations reinforced this shift. “We spoke with another DJ about how much the festival scene has changed in terms of how fans discover music. A lot of people hear tracks first on social media before they even see a set. That’s shifting how all of us prepare.” Their vision extends further, too: “We’d build it like a journey. Start with deep groovy, melodic acts, move into high-energy peak-time, and end with warm, soulful closing sets. A day that reflects all the sides of house music we love.” After this year, they leave with one clear lesson: “That connection you can’t plan, when you play something you love and you see it land exactly how you hoped.”
Tomorrowland has grown sleeker behind the scenes. “It’s much more streamlined now. Back in the day there was more rushing around and figuring things out last minute. Now the crews, the tech, the artist flow, it’s all very dialed in.” That progression mirrors the duo’s own evolution. Sunnery James & Ryan Marciano now treat Tomorrowland less as a stage to play and more as a living laboratory of global house culture. Their enduring presence, their adaptability, and their eye for both detail and emotion keep them central to its story. What they bring home isn’t just memories. It’s proof that Tomorrowland remains the festival where artists and fans reinvent dance music together.
