On October 16th, we're celebrating the relaunch of Klaasje with a special event at BRET Amsterdam from 22:00 to 04:00. Klaasje is entering a new chapter with a new look and a stronger focus on music, events and nightlife. You can expect a night with good vibes and great music, as we are moving from house to hard house and trance. With a carefully curated DJ line-up, we can't wait to make it a night to remember.
