The first wave of acts playing 2026's 25th anniversary edition of A State Of Trance has been announced. The festival returns to Rotterdam Ahoy from 27th-28th February, and will take in a five-hour headline set from A State Of Trance founder Armin van Buuren. In a statement, van Buuren said: "This isn't just another festival, it's a celebration of everything we've built together over 25 years. The two-day 25th anniversary event was initially announced earlier in September. Last month, van Buuren released his 'A State Of Trance Ibiza 2025' mix album.
