DJ Thera will take his audience on a musical journey through twenty-five years of his career. From his early hardtrance roots to the first steps in early hardstyle, from the classics that shaped the scene to the raw anthems that solidified his name. Everything will come together in a setting where energy and connection with the crowd are front and center.
Special livesets
For this occasion, Thera will revive his most iconic albums and live projects, including From The Heart and Training Sessions vs The New Era. On top of that, exclusive back-to-backs are lined up with friends and likeminded artists from the scene, while a dedicated Hardclassics area will cater to fans of the oldschool sound.
The atmosphere will be pushed to the next level with a series of special b2b sets. Expect DJ Thera alongside Jason Payne, Super Marco May and the explosive clash of Degos & Re-Done versus The Geminizers. Exclusive sessions with Geck-o and Caine are also on the program, with the latter reviving his raw classics for the first time in years. This gives the audience not just a trip down memory lane, but also a celebration of the friendships and collaborations that have defined Thera’s career.
