MULTIGROOVE
Since 1991, we've been the underground's voice.
What started in Amsterdam's squatted warehouses and abandoned industrial spaces became the Netherlands' longest-running rave promoter. We didn't ask for permission. We created the space where the underground could breathe, sweat, and dance until the walls shook.
Three decades later, we're still here. Still loyal to the sound that raised us. Still building sanctuaries for those who need the kickdrum to feel alive.
We've evolved from illegal raves to festivals that draw thousands, but we never traded our soul for legitimacy. Every event we throw honors where we came from—the squats, the secret locations, the 90s chaos that shaped electronic music culture.
This isn't nostalgia. This is continuation.
Through Hellbound, we keep hardcore pure and relentless. De Samenzwering channels the driving force of hard techno. Gabberland celebrates the raw essence of gabber culture. Digital Overdose unites every corner of the hardcore spectrum under one roof.
Our community spans generations now. Ravers who were there in '91 dance alongside those discovering the scene for the first time. That's the point. We're not preserving history in amber—we're keeping it moving, breathing, adapting.
If you've found us, you already know. The underground never died. It just evolved.

HOUSE RULES
We've spent three decades creating spaces where people can be vulnerable, free, and fully present. That only works when everyone takes responsibility for the energy they bring to the dancefloor. The dance floor is our sanctuary. Help us keep it that way.
Respect the space
Everyone here came to lose themselves in the music. That's the ritual. Don't interrupt someone mid-trance to chat them up. If they're eyes-closed, fully gone, let them be. The dancefloor is for dancing.
no means no
The first time. Every time. A smile doesn't mean they want to talk. Dancing nearby doesn't mean they want to go home with you. If someone walks away, that's your answer. Don't follow. Don't stare for five minutes straight. Give people space to express their limits, then respect them. It's that simple.
look after the tribe
See someone too far gone to take care of themselves? Help them out or find security. Predators don't belong here. If someone tells you they feel unsafe, believe them. Get our crew involved immediately. We'd rather stop a problem early than have someone defend themselves alone.
