Hidden Secrets - Indoor Boiler Room

A close-up dance journey from hard house and bouncy techno to hard techno, right in the middle of the crowd On Friday 18 September 2026, Hidden Secrets takes over De Helling for an intense indoor clubnight built around energy, heavy sound and a crowd that is close to the action. This is not just another night out. Hidden Secrets brings a boiler-room style experience to Utrecht, where the artists are surrounded by the dancefloor and every drop, kick and build-up feels even more direct. Expect a night that starts with driving hard house grooves and slowly pushes deeper into bouncy techno and hard techno.
