Boiler Room comes to Belfast for a pulse-quickening open-air session deep within Ormeau Park, bringing an uncompromising techno and house line-up that cuts through the city’s summer haze. For one night only, crowds will converge under the open sky for a sweat-drenched odyssey of forward-thinking dance music, broadcast to the world from the heart of Northern Ireland. At the helm is Dutch selector Chris Stussy, whose rolling, groove-heavy sets have made him one of Europe’s most sought-after purveyors of modern house.

Galway’s KETTAMA is set to bombard the main stage with a raw style that’s both high-octane and irresistibly euphoric, raising the temperature for a local crowd well-versed in his breakneck energy. Effy, the fast-rising London DJ and producer, will bring her signature blend of deep techno, electro, and rave for an unrelenting late-night feel. Special Request—a project by Paul Woolford—injects low-end pressure and retro-futurism to the proceedings, harnessing elements of UK rave legacy through his genre-bending sets.

The local scene’s own Holly Lester steps up with a selection that pays homage to Belfast’s clubbing tradition, while Surf 2 Glory round out the bill, marking this as the key date in Ireland’s summer dance calendar. Expect an unfiltered, no-nonsense party and a rare chance to immerse in Boiler Room’s global phenomenon in one of Belfast’s greenest spaces. The dancefloor awaits.

June 28, 2025. Ormeau Park, Belfast.
