About

Plus Instruments is a Dutch experimental project established in 1978 in Eindhoven by Truus de Groot, often called the “Queen of the Dutch Underground.” Emerging from the punk explosion, the project evolved toward experimental and industrial music with largely improvised live performances. De Groot collaborated with artists including Lee Ranaldo of Sonic Youth, James Sclavunos, and Michel Waisvisz.

The cult release Februari – April ’81, recorded in New York, connected the project to the American No Wave scene. Plus Instruments has remained active across four decades.

In Their Own Words

23 Questions · Interview by Maks Giordano · Answered by Truus de Groot

Q1

Truus, you have stated that your "absolute age" is permanently twenty-six. How does this belief alter the physical energy you bring to the stage compared to peers who embrace their elder-statesman status?

TRUUS

Did I say that? Ha ha… well if I may be so bold, you can maybe compare me to the energy of Nick Cave — he's my age — or Iggy Pop for that matter. When I am on the stage I do get quite a bit of energy, adrenaline; it's a magic place where stuff happens.

Q2

You used to play touch-sensitive crackle synths designed by Michel Waisvisz. What is it about touch-sensitive, unpredictable circuitry that attracts you more than stable modern synthesizers?

I still do! I had my own Crackle type Synth built. I will have that with me at the show. What is interesting about it mostly is that it is unpredictable, so you really improvise whether you like it or not each time you touch it. It challenges you! Endless surprises! Un-tunable. Sounds are just different, it has an organic quality to it since the current runs through you and overall it's very unstable. It runs on batteries so it keeps evolving, which I love!

It challenges you! Endless surprises!
Q3

When you arrived in New York in 1981 at age twenty-one, you booked historic gigs by simply knocking on the doors of CBGB promoters. How has the modern digital booking landscape altered the raw, physical hustle of independent music?

Impractical, because you are not able to personally enchant them. Sometimes it takes many layers of people to get to the one who actually makes the decisions. And now they do not want to take any risks. It has to generate a certain income for these venues. Which is a pity because they end up always booking the same shit. Case in point: in my own hometown of Eindhoven there is a great venue, De Effenaar. They have two huge banners with me on it — kinda like a hall of fame thing. It shows a quote from me and all the dates I have played there (there are more, but OK). The other two are The Birthday Party and Sonic Youth. Yet… they will not book me. No way in hell. Hey, I can rent the venue. It makes me quite pissed! You get the picture.

Q4

Your new 2026 album is titled Unnoticed. Do you feel that your role as an early female pioneer of Dutch electronic music has been unnoticed by mainstream music history?

Well, yes! Totally. But maybe I am not assertive enough.

Q5

Your current live set features Richard van Kruysdijk on acoustic drums. How does playing with a live, sweaty drummer alter your synthesizer performance compared to performing with programmed drum machines?

It injects a lot of raw energy and Richard is amazing!!

Q6

You have recently returned to contribute vocals to the reformed Nasmak under the name Nasmak PM. How does it feel to share vocal duties with Joop van Brakel after decades of operating as a solo director?

Frustrating, but it was fun to do it for a few events. Not my cuppa tea though. I am much more into improvisation and certainly minimal rehearsals, if any. That is hard with a 4-piece band.

Q7

Your classic album Februari - April '81 featured Lee Ranaldo of Sonic Youth and David Linton. How did their sharp, No Wave guitar noise challenge the minimal electronic rhythms you brought from the Netherlands?

Fit like a glove actually. In fact, I had been playing noise guitar myself in earlier Plus Instruments line-ups, so it was a thing. Also my electronic rhythms were very analog, messy and crude. Most came from the Putney synth, so it was not a sequencer but more an oscillating pulse, sometimes pots and pans and of course the Crackle synth. Later on I got another home-built sequencer that generated slightly cleaner sounds, but still quite messy. No BPM in sight!

Q8

Your retrospective box set was compiled by Vinyl-on-Demand. How does it feel to have your early, cheaply recorded cassette experiments remastered and preserved on high-grade vinyl?

Absolutely amazing! I am so honored VOD did that — and a great product in the end!

Q9

Lyrically, you have sung "People are stupid; people are bad!". Is your music a cynical critique of humanity, or a joyful invitation to dance despite the horror of the world?

Both.

Q10

You have lived between the United States and the Netherlands for decades. How do the different spaces of Southern California and the Dutch underground influence your writing?

Funny enough it does not matter where I am, I generate in my own kind of world wherever I am. Having said that, certain big cities or strange environments do inspire in a certain way. But I believe how I work anywhere is more thematic, not geographic.

Q11

How do you construct a danceable groove that avoids the predictable, macho cliches of early European industrial and EBM music?

It just happens, and I don't listen to a lot of music — certainly not that kind of music — so I have nothing to imitate. I think doing this so long I've got it down as a trademark Truus Groove?

Q12

Your VOD Fest performance takes place on Sunday on the Inside Stage. How do you plan to use your high-energy, "no bullshit" post-punk set to shake up an audience that is deep into the third day of avant-garde noise?

I thought it was outside? I think the audience will find enough rough sounds in our set, with mean grooves and beats. I aim to please!

Q13

You built early Plus Instruments around the crackle box, a Waisvisz instrument so rare only two of the large ones existed. What did an instrument that unstable and unpredictable teach you about control?

That you can't control it! That makes it fun!

That you can't control it! That makes it fun!
Q14

You were a woman making electronic music alone in a flat in 1978, when that was almost unheard of. Did you experience yourself as a pioneer at the time, or only realise it decades later when people started calling you the Queen of the Dutch Underground?

Much later. I did what I had to do, still do — not much has changed.

Q15

Lee Ranaldo played guitar in Plus Instruments before Sonic Youth existed. What did you hear in him then, and did you sense what he would become?

Well, Lee came from a certain time where that type of noise playing became a thing — that all flowed from No Wave maybe? I would dare to say that it was also inspired by my Dutch and German band friends, like Suspect and Sprung aus den Wolken, who we jammed with and who took screwdrivers and drills to their guitars already. Then the freedom of playing so abstract might be inspired also by Glenn Branca and Rhys Chatham. Lee could actually play though, so he played noise guitar but with a touch of Rock & Roll. The fact that Sonic Youth became so big was perhaps a matter of great timing. But they struggled many years, it was not always easy and not easy to stick with it, but they did and it paid off!

Q16

You perform now by playing live against your own analogue backing tracks from the eighties, sometimes pots and pans. What is it like to duet with your younger self, and does she ever surprise you?

Yes, it always evolves! But I don't only play with my older backing tracks, I often re-make them and then they are re-born yet again — and of course a lot of new material all the time.

Q17

You have said it always comes from your own initiative, that you decide who to play with. In a scene built on collaboration, why has it mattered so much to keep that decision yours alone?

Because that is how Plus Instruments is — it's me, my own formula! It has been since 1978, so why stop now?

It's me, my own formula!
Q18

Your method has always been improvisation with a minimal, groove-based approach. What is the difference for you between improvising and simply not having finished a song?

From improvisation come the best ideas, of course. However, I do put quite a bit of effort into finishing songs once I feel I have something good. Sometimes a song is never finished and keeps evolving, but you have to be open to that.

Q19

You leapt from the Dutch ultra scene to New York no wave, two underground worlds that barely knew each other. What did the Netherlands give you that New York could not, and the other way round?

To be honest I think that NY No Wave hugely inspired the Ultra Scene, but it took its own form. Most important is that you could just do it — you did not have to really know how to play anything. That came from the No Wave movement. I took that into Ultra and went back with it to NYC. There it morphed into more of a minimal electronic dance thing, to counter the overproduced dance sounds of the 80's.

Q20

The project is called Plus Instruments, with rotating people around a constant you. Is the plus a way of saying the collaborators are additions to something that is fundamentally you alone?

I just like the words Plus Instruments — and in fact that is what it is: humans Plus Instruments.

Q21

You have kept this going for almost fifty years across continents and generations of gear. What is the thing you are still chasing that you have not caught?

A world hit? Ha ha ha… No, but really, I am intrigued by what makes a world hit. It can even be quite abstract. And all it takes is one hit and then you can make the world better. As far as gear, my curiosity never stops discovering weird instruments.

Q22

Your early sound came from crappy gadgets and whatever came to hand, always after a gritty, dirty overtone. Now clean digital sound is effortless and free. Do you have to work harder now to stay dirty?

I am not interested in clean digital sounds. That is why I always search for the dirtier sounds even on clean synths. My arsenal of instruments is pretty low brow and still quite a few toy things and self-built stuff. I had a great time recording 50's / 60's test and measurement equipment at Willem Twee studios in Den Bosch (NL). I am incorporating some of that in my forthcoming album.

Q23

You have a photo book about your early New York life and a scene that has become mythologised. When your past becomes a museum piece, how do you keep making new work that is not just a footnote to it?

Always forward. Never go back. I wrote a song about that too…

But in all seriousness, I also collaborate with other people like Cosmo Vitelli, Miguel Barella (Blue Beast), Woody Veneman and now with Richard van Kruysdijk and Golden Bug. It is hugely inspiring. All of this keeps me growing as an artist and vice versa, always learning more.

Always forward. Never go back.
