Have you spotted it yet?

A new gadget has taken its place in the OSR container; a custom DJ isolator, built by and inspired by the DJs who bring the heat to the OSR booth.

First seen (and heard) during the Vierdaagse Feesten, it has quietly become part of the booth ever since. No-nonsense, just function!

The idea came from , whose passion for technology, sound systems, and analog warmth led to the creation of this Isolator, designed from scratch, not for the market, but for the community.

This one’s built for those who live for the tactile feel, demand full-frequency control, and know the difference real analog sound shaping makes

Curious?
Hop in the OSR booth and give it a spin.
You might not want to play without it after.

5 Tips for Vierdaagsefeesten 2025

The Vierdaagsefeesten are back, one full week of music, madness and marathon dancing across the entire city. Whether you’re crawling from café to club or floating through festival fields, we’ve rounded up five artists we’ll definitely be catching this year. Consider this your OSR cheat sheet. 👀

Aldonna @ Umami - Sunday, July 13
After a steamy set at Het Nest last year, Aldonna returns to close out Club Voerweg. Think progressive house and trance with a silky nod to the ‘90s and ‘00s, she blends nostalgia with a fresh edge, always riding the groove. This one’s for the sunset heads and deep diggers.

DJ Godfather @ Ghet 2 Werk - Monday, July 14
A true Detroit OG. DJ Godfather helped shape the entire ghetto tech genre, and on Monday, he’s flying in to shut down Club Voerweg. It’s raw, fast, unapologetic and a rare chance to catch a living legend live. Do not snooze on this one.

Amor Satyr & Siu Mata @ Planet Rose - Thursday, July 17
Parisian chaos agents Amor Satyr and Siu Mata bring their explosive speed dembow sound to Planet Rose. Expect a genre-melting blur of tribal techno, baile funk, jungle, and all sorts of sonic curveballs. It’s going to get sweaty and weird in the best way.

CHAMOS @ Feels Right - Wednesday, July 16
The duo behind Feels Right is cooking up a heady fusion of West Asian percussion, bass pressure, and modern club sounds. CHAMOS have been making waves with their remix of Berzi Berzi, and if their online presence is anything to go by, their Wednesday night takeover is set to be pure heat.

Papa Nugs @ CALOR - Tuesday, July 15
Straight from London, Papa Nugs comes with playful house grooves and a strong dose of UK swagger. He’s a label boss, a producer, a DJ, and most of all a party starter. Rough around the edges in all the right ways, and just the kind of chaos we like midweek.

The Vierdaagsefeesten run from July 12-18. We’ll be broadcasting live from our container at Valkhof Festival every day, 15:00-20:00. drop by, wave through the window, or catch the stream via opensourceradio.nl.
