Tales from the Echobox: JLSXND7RS

Interview by Passion Dzenga and Chalice Cox-Hynd | Photography by Fien Bulsing

Launching in 2021, Echobox has been forging a path for community radio by showcasing the diverse characters and concepts that surround their station. In this feature, we will be looking into one of the broadcasts that you can tune into, so get locked in and don’t touch that dial. 

Echobox resident JLSXND7RS doesn’t talk about grime like a genre; he talks about it like a force. An energy that can travel, mutate, and still stay true, even whdocden it’s born in one city and raised somewhere else entirely. Long before the Dutch scene had any real infrastructure for 140, he was already tuned in: not through hype or trend cycles, but through obsession, the kind that starts with family instruments in an attic, turns into studying producer credits in The Source Magazine, and ends up on late-night forums where exclusives were passed around like contraband.

Growing up Moluccan, music wasn’t an extracurricular; it was culture. And when UK sounds began bleeding into his world, they didn’t feel foreign. Hearing DJ Zinc’s “138 Trek” in Amsterdam opened one door; catching Dizzee Rascal’s “I Luv U” on TV – gabber-style 909 kick drums colliding with rap – kicked the next one clean off its hinges. From there, it was instant messenger group chats with producers like Spyro and Teddy Silencer, digital dubplates in the inbox, and Fruity Loops learned through community rather than classrooms. While others chased validation through parties, JLSXND7RS was building in isolation: outside the big cities, away from noise, developing a relationship with the UK that was direct and long-term.

That connection eventually became physical. London wasn’t a pilgrimage. It was an extension of a network he’d already earned his way into. From early collaborations to being embraced by key figures, he speaks about UK support with the kind of disbelief usually reserved for origin myths: Slimzee driving him around the city, opening doors, showing real love. But the deeper story is what London unlocked sonically, a “full-circle moment” where rhythm and intent snapped into focus.

Now, that same curiosity has pushed him far beyond the boundaries people expect from a grime producer. Through Scratcha DVA, Surreal Sessions, and a deep dive into South African sound, he found Gqom’s raw minimalism and recognised the same spirit that made grime matter in the first place: making something heavy from limited tools, prioritising swing and groove over polish. It’s a perspective that explains everything from his uncompromising radio selections to a Hyperdub collaboration with Ikonika, to the global ripple effect of his “Silo Pass” remix, a track he made almost casually, only to watch it bridge scenes worldwide.

This tale from the Echobox is less a career recap than a map of how a sound survives: through family, through underground networks, through the stubborn refusal to play obvious tunes, and through the belief that music is something you learn, guard, and pass forward and not just consume.

You’ve been pushing this sound for some time. Before we even get to grime, where did music start for you?

Music came first, before grime. I started really young. It's kind of funny looking back. I grew up in a musical family. I’m Moluccan, so music is just part of the culture. At my grandma’s house, everybody gathered, nine children, and everyone played something. 

So music was always around. I started off on drums, which I loved. But when I was around 12, my older cousins got into gabber and trance, and they gave me all their hip hop CDs—Snoop, Wu Tang, all that good stuff. I became obsessed. I’d just sit there drumming along to them in my uncle's room. It was my way of vibing with that sound, and it really shaped my love for rhythm and beats as I got into different genres later on.

I wanted to know how things were made. I was a nerd with it, reading CD booklets, checking producer credits, buying magazines like The Source, looking at what got the five mics and ordering CDs from the record store.

So what was the moment UK sounds really grabbed you?

Alright, so here’s how it went down. It all started with garage music in the Netherlands. I was at a party one time, and there was this DJ - by DJ Zinc - playing a track called “138 Trek”—it blew my mind! I couldn't believe the vibe and the energy. I wanted more of that sound. Then, I stumbled upon Dizzee Rascal's 'I Luv U' and it hit me; he was rapping over those gabber kicks. I was like, 'What is this magic? I need to know more!' I started digging deep online, finding all the grime I could, joining forums, and chatting with artists. I met people from London through those spaces, and added them on MSN. That’s really where grime became a big part of my life. It was a whole, wild journey that really opened my eyes to the scene."

That early internet grime era was crucial: forums, MSN, exclusives flying around. What did those spaces mean for you outside the UK, and how did they shape the way you started producing?

Those spaces meant everything, because that’s how you got the music and the community. At first, I wasn’t producing like that; I was just a serious listener. Everyone wanted to be the guy with the exclusive tunes, so being in those MSN groups was the whole thing.

I’d be in MSN group chats with people like producers. That’s how you’d get the files. People would send you exclusives straight to your inbox, and you’d be sitting in the Netherlands with tunes people couldn’t even get elsewhere. That was the culture: the feeling of being close to the source, even if you weren’t in London.

Then, through that network, I started trying production. Someone showed me Fruity Loops, gave me a copy, and showed me the basics. But even then, I never really connected with the Dutch scene the same way. The only people I was truly connected to here musically were Axel from NoizBoyz and a couple of others like SunOC. I wasn’t watching what everyone in the Netherlands was doing. I was in my own world, and living outside the big cities helped that. No distractions, no noise, nobody telling me what to make. I just developed my sound and my relationship with the UK.

Do you feel like something got lost when grime moved away from those tight-knit online communities, the dubplate mentality, the competition, or did it need to evolve?

It definitely changed. Back then, it was competition, everyone guarding tunes, everything feeling exclusive. I’ve still got unreleased tunes from almost twenty years ago. When I play them to certain people, it’s like, “Ahh you got that too.” But it depends on where you are.

In London, that exclusivity means something very specific. In the Netherlands, most people don’t even know what they’re hearing, they’ll just say “this sounds cool,” not “that’s a rare 2005 white label.” So the meaning of exclusives changed, but the culture still exists.

And the blog culture used to be wild, too. Back in the forum days, someone played a VIP and within hours, there was a rip going around. Now it’s different, but don’t get it twisted, the headsy culture is still there. People still want to own things other people can’t access.

 

Grime has always been framed as London-centric, but you built a real identity from the Netherlands and not even from a major city with infrastructure. How much of that is your roots, and how much is the UK connection you built online?

First, grime. It’s energy. It’s not just a sound. People sometimes talk about it like it’s only tied to one place, but the reason it connected with me is because of where I’m from.

Where I’m from, there is poverty, survival, and madness. And in the Moluccan community, we’ve got our own history in this country. Our neighbourhoods were built like that on purpose. A lot of toxic stuff came with it, drugs, rebellion, tension with the government, and the community became very closed off. That’s real! You grow up with that in your head as a kid. 

Then living in London? Man, it was a wild ride. You meet so many people, and everyone’s grinding, trying to make it happen. Honestly, it was that mix of the hustle and the creativity that really shaped me. You learn a lot just being around all that talent and vibe.

So when I lived there and connected with UK people later, they’d tell me, “Bro, you’re just like us, how is that possible?” But it’s possible because the environments are similar. The infrastructure might be different, but the reality of certain neighbourhoods isn’t that different. 

Pirate radio built grime, but you’re still heavy on radio in the post-pirate era. What does radio mean to you now, and what did it mean when people like Slimzee and the other key DJs backed you early?

It meant a lot because those are serious people. Slimzee is the first big DJ to really play my music and push it: it was around 2014 and my track 'Undertaker.' was really making waves, and Slimzee got wind of it and that was it. He is genuinely one of the realest people in the scene; he did for me what he’s done for other key artists. When I came to London, he told me to call him. He drove me around, showed me everywhere. I was in his family home with his mum, all of that. That’s not normal.  Since then he's been a huge support for me. I can't tell you how many times he’s messaged me asking about new stuff. He's just genuinely invested in my journey. Plus, if you check his socials, he's always posting about old music—it's clear we both have a love for those roots.

Radio now, for me, it’s still important, but the function has changed. I do radio to show people I’m a sick DJ too, not just a producer. And I’ve got endless music, unreleased, rare, weird stuff, stuff people won’t hear anywhere else. I don’t play obvious tunes. Especially in the Netherlands, the clubbing scene can be so cliché, people want the same instrumentals, the same moments. I hate that. We should be teaching people music, showing new things. With Echobox I’ve got freedom: grime, trap, sometimes techno, whatever. I’ve earned my stripes. Now I can have fun.

After years of grime, you pivoted into Gqom. What unlocked that shift? And how did working with Scratcha and Surreal Sessions change how you think about rhythm, space, and sound design?

The shift came from hearing South African sounds properly and then doing my nerd research. In London, Wiley was playing a lot of Amapiano – softer stuff. That was my first real exposure.

But Gqom hit different. After that Boiler Room Festival, I went deep. What is Gqom, where is it from, what’s the history? I love the older, raw 808-driven style – percussion, 808, bass. I don’t need much more than that. That’s why stuff like old-school gqom connects for me. It’s raw, and it has groove.

Surreal Sessions taught me a lot about the South African approach, the spacing, the swing.

And the bridge is limitation and approach. A lot of producers there aren’t working with powerful computers or crazy plug-ins. They use what they have. Fruity Loops stock sounds, simple tools. Over here, we can get too clean, too designed. I tried recreating log drums with my own synths and using grime-style sound design what ive noticed is that they want the sound to stay what it is. If you make it too polished, it stops being Gqom; it becomes like a caricature. So I learned to respect the rough edges. That’s the authenticity.

You talk a lot about the culture, the scene - backers like Slimzee and connections that become real friendships, across not just grime but gabber and techno. Is there a connection there with the harder genres and keeping it on a level?

So, I've got this theory about it. Making music is like a release, right? You pour all your anger and frustration into it, and then it kind of calms you down. It’s almost like meditating through the music. You hear some of the hardest styles, and yet the people behind them are often super humble and down to earth. It’s like when you lay out your feelings in the music, it transforms that energy and makes you chill as a person. I think that’s why you see a lot of nice people in genres that go hard; they’re turning all that intensity into something beautiful.

Beyond being a producer, an engineer and managing Chamber 45, you’re also a DJ. How does that fit in to the bigger picture for you?

Being a DJ for me is a bit wild. Back in the day, if you weren’t producing, you weren't really getting booked. So, I made tunes to swap with other DJs; that was how it worked. I think everyone wants to be a DJ now, but in grime, you had to have that dual skill. I’d make a track, and big DJs would hit me up for it, and I’d share tunes, sometimes even unreleased gems from big producers. It’s funny because the same thing happens back to me—now I have tracks that people shouldn’t have! It’s all part of the grime culture.

What’s your process when it comes to producing? What inspires you?

My process really depends on what I'm feeling at the time. I draw a lot from the grooves in songs I love—like 80s pop, Madonna, Billy Idol, and George Michael. I also stumbled upon some weird rock music from my dad's old CDs, which sounds almost like the background music in old animes—those crazy instrumental tracks that have a unique vibe. I try to capture those rhythms and emotions when I create. Interestingly, I don't really listen to grime as much anymore; it's more about the eclectic influences that inspire me in different directions.

If one era was about proving yourself, what’s 2026 about, creatively, personally, and in terms of what we can expect next?

2016-2019 was trying things, building, linking with people, bridging worlds. I was moving between grime and dubstep, in the middle, people like Mala cutting my tunes to dubplate, people across scenes playing my music. London gave me that full-circle moment where I understood my sound on a deeper level.

2026 is about a bigger, more personal body of work. I’m working on an album that’s literally everything I like making, all the genres that shaped me. I’m into old “freestyle” music too, that 80s Hispanic electro singing/rapping vibe. I play it in my shows, and it connects to things in Brazil too.

I’m also experimenting with Scratcha’s drum kit in ways people wouldn’t expect: drum techno, drum trap, drum drill, pushing the tools into different spaces.

Speaking of creating and building, you recently went viral with a song that’s been out for a decade. How did that come about?

Yeah with my song Marching. So Makten, he was going outside with his decks, and then he went to Shoreditch with D Double E. And he played my song. And this went crazy viral. Like, you know, Popcaan, this Jamaican artist, he posted it on his Instagram. Like, big people from the world were all posting on Instagram. And that was, for me, that. That’s been a highlight in my musical career, basically because I made that song 10 years ago, and for it to come back was crazy. The song also got used during Red Bull Culture Clash where D Double E was part of Jamaican artist Spice team.

There's even an interview that Makten did with Chucky, from London. And they touched down for 10 minutes about me, like, “who is this guy who made the song?” And they go on my Spotify. Oh, he made this and he made that. It's very funny to see, cute. So big up Makten. 

When that happened, a lot of big people on the scene messaged me, you've got one meaning. I've got a timeless banger. That's my pile, my oil, whatever you want to call it, that's mine, if that makes sense. So I have a certified classic in grime. So like, yeah, that’s it forever now.

Last one: the name JLSXND7RS - it’s such an enigma and you don’t really talk about it. Can we get the big reveal?

Alright, so the name JLSanders—it’s got a bit of a backstory. The 'J' is a nod to me, Justin, you know? And the 'L' comes from this Dutch soap opera character named Ludo Sanders, who's like the tough guy you don’t mess with, kind of the Phil Mitchell of our scene. I thought that was fitting. There’s more to it but I’m going to keep everyone guessing.

Tune in to Echobox, broadcasting from below sea level every week, Wednesday until Saturday.
