Forever 25 is back: the non-stop extravaganza where we look back at the old days of Kater while dancing into the future! 50+ hours of music and performances as old and new friends come together. Join the 25 club! Limited presale. More tickets are available at the club. A presale ticket does not guarantee entry, and the club reserves the right to refuse admission. In case of refusal, the ticket price will be refunded via RA (excluding fees). 5€ re-entry fee may apply. Please note that the non-smoking regulations apply in the club. Smoking is only allowed in the designated outdoor area.
