Lässig returns to Primo's DDD at Toekomstmuziek on 28 March 2026 for its fourth edition, bringing our signature blend of bouncy, spacey and progressive house back to Amsterdam West. After a successful third edition at the venue, we are expanding the format with three exclusive B2B sets, curated specifically for this night. Expect a journey through high-energy house, deep and rolling grooves, proggy undercurrents and 90s-inspired trance and acid flashes - a sound that moves, delights, and lifts you up! For this edition, Lässig co-founders cathü, Ketrix and Kiwitz invite a carefully selected group of Amsterdam-based artists for three one-off collaborations: cathü b2b JUSTINE Sexy house and proggy tension meet high-energy, feel-good grooves. Scottish-born Justine is known for her playful house sound and infectious energy behind the decks. Kiwitz b2b Manscream Deep, hypnotic and rolling. Manscream’s acid swells and forward-moving grooves blend seamlessly with Kiwitz’ deep & proggy beats, creating a set that builds patiently and hits hard. Ketrix b2b almostDan Punchy progressive house, trancy layers and raw 90s acid flavours collide. almostDan’s groovy, up-tempo style meets Ketrix’ eclectic mix of prog, trance and breaks - energetic, bouncy and unapologetically club-focused.
