The Big Absences of Tomorrowland 2025 Lineup; Who’s Missing and Why?

Drawing over 400,000 fans to celebrate unity, creativity, and auditory innovation, Tomorrowland turns the Belgian countryside into a throbbing epicenter of electronic dance music every summer. 2025 is not an exception; the roster announcements for the festival are analyzed with the zeal of a Grammy nomination list. While the comeback of the Swedish House Mafia and nostalgic partnerships excite fans, the lack of major names like Tiësto, Alesso, and Keinemusik has generated interest and controversy. This change speaks to the development of Tomorrowland as well as the direction in which EDM itself is headed.

Where Are Alesso, Keinemusik, and Tale Of Us?

Tiësto, a Tomorrowland essential and trance-turned-mainstage icon, is absent from the bill for the first time in more than ten years. His explosive sets have long been associated with the highlights of the festival, including a historic 2016 mainstage closing. Alesso, whose songs like “Heroes” and “Years” marked the 2010s EDM explosion, is glaringly absent as well.

Although both musicians are supposedly concentrating on studio projects and residency, their absence leaves a hole for those yearning for euphoric singalongs, especially when it comes to Alesso. The Swedish producer has gone radio silence for two months now. He is supposed to play at Aspen on the 14th of January and after that at Ultra Music Festival in Miami.

With Keinemusik (the trio of &ME, Adam Port, and Rampa) and Tale Of Us providing hypnotic, genre-defining sets, the 2023–24 lineups of the event leaned most toward techno and melodic house. Given their recent supremacy, their 2025 omission begs questions.

Especially lacking as solo performers are Keinemusik’s members.

Recent mainstages have seen W&W’s high-energy trance, Dom Dolla’s tech-house rhythms, and emerging artist Mau P predominate. Their absence hints Tomorrowland might be experimenting with new sound limits. Mau P was a 2024 standout with his breakthrough songs “Drugs From Amsterdam,” but his emphasis on a debut album and U.S. tours probably drew him elsewhere. W&W’s big-room sound, meanwhile, seems incompatible with the recently stated “throwback” attitude of the festival.

Who’s coming back? Swedish House Mafia are back in the golden era

On the other hand, the Swedish House Mafia (SHM), whose 2018 reunion was a cultural reset, marked the triumphant comeback in sharp contrast. Together with a rare Axwell b2b Steve Angello b2b Sebastian Ingresso throwback set, their headline slot promises a rebirth of the golden age of progressive house. Eric Prydz, whose HOLO performance is still a technological wonder, and emerging performers like Anyma b2b Solomun, combining melodic techno with theatrical flair join them.

Does 2025 represent a new blueprint or a transitional year? The roster suggests trying to accommodate several demographics by balancing legacy artists (SHM, Prydz) with innovative combinations (Dubvision b2b Third Party). But the lack of trendsetting creates holes in the progressive house niche even with MRAK (missing as a solo act despite his collaboration with Anyma).
