I will be playing a live, improvisational set for modular synthesizer, found objects and SoundBox at Basic Electricity Berlin on Friday 28 September 2012. Joining me will be video artist Vanessa Ramos-Velasquez with her live electronic microscope visuals. This will be our first, exploratory outing with the A.LIVE bio-art project, and we’re both quite curious to see how it goes. Hope some of y’all out there can make it.
Incidentally, the audio in the above video comes from the soundtrack of Machine Deva, the recent collaboration I did with my father, Steve Holzer. Interesting to hear it in another setting… Machine Deva recently won the Best Experimental Film prize at the Columbia Gorge International Film Festival. Way to go, Dad!
I will be offering copies of the Machine Deva soundtrack on CDR and DVDRs of the film itself some time in mid-November. Due to the extremely detailed nature of the hand-animation, which seems to be hopelessly corrupted by any sort of compression process, Machine Deva will never likely get put online. So unless you happen to be around when Steve or I screen it, this might be your only chance to view this remarkable work. Get in touch if interested…

The Rainforest project at the LAK Festival for Nordic Sound Art in Copenhagen was a complete success on many levels. The organizational team was fantastic, even without considering that this was their first ever event. While they planned for a modest 100 visitors for each day of the event, the total number turned out to be about 1500 in total. The Rainforest concert opened the festival, and continued as a live installation each day. Many thanks to Rainforest co-organizer (and true soul buddy) Mads Bech Paluszewski-Hau as well as participants Anders Børup, James Brewster, Ejvind Juul Chang and Kristian Hverring for their energy and dedication, as well as to curators Jonas Olesen and Sandra Boss as well as the whole LAK team for a great weekend.

Posted in Announcement on August 16th, 2012 by admin
Mads Bech Paulszewski-Hau and I will be running the “Rainforest” series of workshops at two events in Denmark next month: the LAK Festival in Copenhagen (6-9 September 2012) and the BY i BY Festival in Aarhus (14-16 September 2012). There are still spaces in both workshops, particularly the Aarhus one (which will be outdoors!), so please get in touch if you are interested at MACUMBISTA at the domain GMAIL dot COM.
Regsnkov 2012 is a contemporary re-interpretation of David Tudor’s series of compositions from the 1970′s entitled Rainforest. It uses various types of sonic transducers to play live sounds through a selection of resonant, found-metal objects in the performance space. A matrix mixer allows the sound from any of the performers to be sent to any of the objects, creating an immersive, tactile and spatial sonic experience.
The project is developed in a workshop format with up to 8 participants over a period of several days. The participants will work from the bio-acoustic model of an actual rainforest, where it is necessary for each species’ survival that they can both hear and be heard within their own niche of the busy forest soundscape.

crippled black phoenix–(mankind) the crafty ape[2012] wovenhand–live at roepaen[2012]
Getting the computer out of my live sound was the best thing that ever happened to me. When I work with the modular synthesizer, I feel like I have a piece of clay in my hands which I can squeeze in any direction I choose. This short improvisation was made during filming of the documentary “Learning to Listen”, on sound artists in several European cities by London College of Communication students Dann Linn, Marianna Sangita and Andi Spowart.
I’m just back from my Swedish gig, where I spent the weekend gazing longingly at leggy blonds and red farmhouses, slapping mosquitoes, sipping expensive beers and teaching 25 people to build small noise-boxes in the summer sun. Concert went great, with a huge Function One sound system in the gigantic, resonant Mimer mine-shaft hall for that all-over body bass-massage kind of feeling. One of the best parts was that, some weeks ago, I dreamt that two friends from Estonia came to the festival with me. When I wrote them about it, they replied, “Roadtrip sounds like a great idea! See you soon!” So they did.
Big thanks to Sol Andersson and Johannes Ahlberg for the invitation and John Anker Corneliussen for the sound! Also managed to catch a few great sets, most notably by Carl Michael von Hauswolff and the lovely drone duo Kyrkan. Just as awesome, and tasty to boot, was James Brewster‘s Electro-acoustic cafe–a mic’ed up espresso stand with the option for extra delay or wah on your foamed milk.

Another great thing was the wide range of folks who dropped by to build these little Neanderthal instuments–people who by and large would never show up at an “experimental noise” gig suddenly discovered the insane, child-like pleasure of making their own noise. A selection of these good people can be seen above. Thony Ekström has posted a 28 minute video of the workshop presentation here. I like the part where the orchestra warms up in the beginning…
I spent quite a bit of July working on this chopper with a student named Alvaro Ayuso. He didn’t quite finish it… a problem if you’re a young Spanish dude with too many friends around I suppose. Synth building is a solitary pursuit. So consider this a work in progress. Good going so far, amigo, now let’s bring it on home!

old man gloom–no[2012 hydra head] om–advaitic songs[2012 drag city] swans–live at berghain[04 aug 2012 berlin](looking forward!)
The lovely folks at the Norberg Festival in Sweden have arranged for me to do an outdoor SoundBoxes workshop as well as play a concert in the super-echo-chamber mine-shaft-house there.
For the workshop, I will have a tent with some tools and parts set up all day on Thursday 26 & Friday 27 July. The parts kit for the workshop costs SEK 100, and includes all the electronics components, speaker, amplifier, microphone and a cigar box of your choice. Workshop participants will have a chance to perform with their boxes on the afternoon of Saturday 28 July at 13.30.
During the concert on the evening of Saturday 28 July, I will play an improvisation for found objects, speaker box and self-made electronics. Norberg is about the only place I could imagine The Bug sharing a stage with Trevor Wishhart, and I’m looking forward!

The MUU Gallery requested info-sheets for each of the instruments I am showing there. A whole weekend of vector-scribbling later, I present these examples of my mad Inkscape skillz as testament to the fact that I probably should get more sunlight this summer…
This box was created from a found children’s karaoke toy specially for the MUU Invisible Time exhibition, Helsinki (FI). It features a voice-changing circuit, condenser microphone and loudspeaker mounted in an antique wooden box, and has been equipped with “bend points” where physical contact with the circuit changes the sound.
1) On/Off Switch
2) Volume Knob
3) Input Jack
4) 9V Power Input: for battery or wall adaptor
5) Speaker
6) Bend Points: touching two of the screws together with your finger can “bend” the sound of the instrument, or flip one of the switches to hold a certain sound
7) Condenser Microphone with Flexible Neck
To Play:
A) Press the On/Off Switch, you will see a small light above the Speaker when the box is activated
B) Speak into the Condenser Microphone
C) Adjust the Volume Knob to lower the level, raise it or create feedback
D) Feedback can be also created by lowering the Microphone nearer to the Speaker
E) Experiment with the Bend Points using either fingers on the screws or the switches
F) If the sound dies out, speak into the microphone again
This instrument is for sale, price EUR 260.
Macumba Benjolin
Derek Holzer
2012
The Benjolin is a circuit designed by Rob Hordijk from the Netherlands. It contains two oscillators (one slow and one fast), a band-pass filter and a circuit Hordijk calls the “Rungler”, which allows chaotic feedback possibilities between the different parts of the circuit. This one has been customized with an old silverware case, a built-in amp and speaker and a patchbay for further chaotic interactions.
1) On/off Switch
2) Inputs: the four left-hand-side jacks are inputs, don’t unplug these. The black connection with the red cable connects to the speaker. The other input jacks connect to different parts of the oscillators.
3) Outputs: the eight right-hand-side jacks are outputs, play with these. The black jack is the output of the filter. The others others are different parts of the oscillators.
4) Volume knob
5) Output jack, for plugging into other SoundBoxes
6) Speaker: this is turned off when something is plugged into the output jack
7) Filter Controls: these will only change the sound when using the black output jack
8) Oscillator Controls: these change the frequency and chaos levels of the oscillators
To Play:
A) Flip the On/Off switch upwards
B) Adjust the Volume Knob
C) Create feedback by plugging the blue cables from the left-hand side into the different output jacks on the right hand side
D) Listen to different parts of the synthesizer connecting the red cable from the black jack on the left-hand side to any of the output jacks on the right-hand side
E) Use the top row of knobs to adjust the two oscillators
F) Use the bottom row of knobs to adjust the filter, and remember you only hear the filter when the red cable is connected to the black output jack
9) The Macumba Benjolin requires two VERY FRESH 9V block batteries to operate properly
This instrument is from the personal collection of the artist. Customizations of many electronic music circuits are available on request.
M79 Super
Derek Holzer
2009
The smallest synthesizer I have ever made, the M79 Super was built during the Piksel Neanderthal Electronics workshop in Bergen (NO). Here, three oscillators, a tiny speaker and two sound-reactive LEDs are placed inside a beautiful, old, palm-sized flashlight from the 1970’s.
1) On/Off Switch
2) Third Oscillator On/Off Switch
3) Oscillator Frequency Control Knobs
4) Output Jack: to connect the M79 Super to larger speakers
5) Very Small Loudspeaker
6) Two Audio-reactive LEDs: one of these displays the waveform of Oscillators 1+2, and the second displays the waveform of Oscillator 3
To Play:
A) Slide down the On/Off Switch located on the side of the object
B) Flip the Third Oscillator On/Off Switch up or down to activate/deactivate Oscillator 3, and notice what effect it has on the sound
C) Adjust the frequencies of the different Oscillators
D) You can make a filter by covering the small Loudspeaker with a cupped hand or your mouth
This instrument is for sale, price EUR 130.
Electric Spring II and III
Derek Holzer
2012
These are simple, resonant drone boxes using the feedback between a simple contact microphone with a coil-spring and the speaker to make rich harmonic sounds or metallic reverb effects. These were created in an edition of three for the Electric Spring Festival in Huddersfield (UK).
1) On/Off Switch
2) Volume Knob
3) Input Jack: other kinds of microphones or instruments could also be connected here
4) Contact Microphone + Spring: this microphone picks up physical vibrations rather than sounds from the air. It has a resonant coil spring attached to it which makes the drone and also can be used as an “antenna” to search for new sounds
5) Speaker
To Play:
A) Turn Volume Knob all the way to the left
B) Place the Contact Microphone across the Speaker
C) Flip the On/Off switch upwards
D) Adjust the Volume Knob until you start to hear a tone
E) Adjust the position of the Contact Microphone + Spring and the Volume Knob to find new sounds
F) You may gently touch the Speaker with the Spring, but please do not press hard or you will damage the Speaker
These instrument are for sale, price EUR 80 each.
SoundBox I
Derek Holzer
2010
This was the first SoundBox instrument I created in 2010. It uses feedback and the physical vibration of the speaker cone to create different kinds of chaotic sounds.
1) On/Off Switch
2) Volume Knob
3) Input Jack: other kinds of microphones or instruments could also be connected here
4) Speaker
5) Contact Microphone: this microphone picks up physical vibrations rather than sounds from the air. It has two “antenna” attached to it to search for new sounds.
To Play:
A) Turn Volume Knob all the way to the left
B) Place the Contact Microphone across the Speaker
C) Flip the On/Off switch upwards
D) Adjust the Volume Knob until you start to hear a tone
E) Adjust the position of the Contact Microphone and the Volume Knob to find new sounds
F) Place some of the found objects provided in the speaker and see how the vibrations move them around and change the sound
This instrument is from the personal collection of the artist, and is used frequently in performance.
SoundBox II
Derek Holzer
2010
The second SoundBox I built, this one remains a bit incomplete–it looks better than it functions. Besides the normal SoundBox microphone/amplifier/speaker feedback loop, this one was intended to have a small synthesizer circuit which would alter the sound as it passed through. This part didn’t work out so well, but I left the controls to remind me that one day I should fix it!
1) On/Off Knob
2) Three Useless Controls
3) Input Jack: for Contact Microphone or other sound sources
4) Speaker
5) Contact Microphone + Spring: this microphone picks up physical vibrations rather than sounds from the air. It has a resonant coil spring attached to it which makes the drone and also can be used as an “antenna” to search for new sounds
To Play:
A) Turn the On/Off Knob clockwise, you will feel a click when the box turns on, but please don’t expect it to control the volume as well!
B) Don’t bother with the Three Useless Controls either, they’re only decorations at this point
C) Adjust the position of the Contact Microphone + Spring to find new sounds
D) You may gently touch the Speaker with the Spring, but please do not press hard or you will damage the Speaker
This instrument is from the personal collection of the artist, and is a work-in-progress.
Derek Holzer: live SoundBox Performance at MUU Gallery, Helsinki 07 June 2012. Video by Rita Leppiniemi.
Filmmmaker Maren Sextro created this portrait of me for Groove.de in May 2012. Together, we visited the flea market and my studio, and spoke about my approach to sound, performance, “circuit bending” (a term I rarely use to describe my own constructions), DIY electronics and self-education.
Maren was kind enough to send me an HD version so that I could present this without the disgusting advertising, so once again I am in her debt. Enjoy.
Helsinki Show
Next week I make a quick trip to Helsinki, where the MUU Gallery will be opening the latest “MUU for Ears” show. I will be showing one of the “nonlinearity suite” videos, playing a live set for small analog synth, soundboxes and found objects on 7 June and leaving a few artifacts there for the two-week run of the show. Some of these artifacts may be for sale. I will post more on this before I depart.
Workshop: May 26 & 27, 2012, Time 11-19
Workshop Venue: NK Projekt, Elsenstr. 52 2HH 2Etage, Berlin Neukoelln
Presentation + live Macumbista set: Sunday May 27 2012, Time 20.00
Presentation Venue: O’Tannenbaum, Sonnenallee 27, Berlin Neukoelln
Discover the hidden sonic qualities of objects from our everyday world in this workshop, combining the arts of electronics, noise, sculpture and collage. The basic elements we will employ are a wooden box, a speaker, a small audio amplifier, and a contact microphone. To this, brave box-builders will add their own found objects, graphics, images, memories and ideas to create a unique electroacoustic cabinet of curiosities.
No previous electronics experience is necessary for this workshop. Each participant is required to bring several items to the workshop, please see below.
TIMETABLE
Day One: Introduction to simple noise/electroacoustic electronics, circuit soldering.
Day Two: Box-building, decoration and collage, experimentation with found objects as sound sources.
Final Presentation: All participants will present their finished soundboxes to the public at the end of the second day!
WHAT TO BRING
I will provide most of the tools and materials necessary for constructing the box, however there are a few things you should bring yourself:
1) A BOX: This should be made of thin wood or very strong cardboard. Plastic can be also used, but it doesn’t sound very good. And please, no metal! It is too difficult to cut and drill with the tools we will have. This box should be a minimum of 10x10x4cm, or bigger if you want to use a larger speaker or have more room to decorate and add objects. Cigar boxes, small suitcases, instrument cases or jewelry/silverware boxes are all good things to look for. At least one side of the box should be no more than 5mm thick, to allow the hardware to be mounted.
2) A SPEAKER (OPTIONAL): I will have a selection of speakers for participants to use. However, if you have something special please bring it along, but please make sure it fits in the box you have chosen!
3) FOUND OBJECTS: Please bring as many found objects as you can to decorate your soundbox or use as a sound source via the contact microphone. Bones, shells, small sticks, bells, strings, wires, springs (especially!) or anything else made out of solid yet resonant material make great sound sources. Photographs, cloth, leather, paper or any other kind of material can be useful for covering the box and making collages. Paint, markers and pens may also be useful.
4) EFFECTS PEDALS (OPTIONAL): Any kind of battery-powered effects pedals, such as distortions, filters or delays, can be very useful in creating more nonlinearities in the feedback loop.

ZAGREB
Sometimes when I think back, all my workshops seem to go by this fast…
The participants in Zagreb were great, super-motivated and highly imaginative. Each and every one of them made some incredibly special and unique SoundBox during the two days we had together, and even played them too… We also squeezed in an early morning trip to the local flea market to put the shop back into workshop. Big thanks to Deborah Hustic for organization and hospitality! Was also great to see some old friends around town, such as Ivan “Kliff” Marusic and Borut Savski.
I think my favorite SoundBox from this workshop was this one, crafted from the end of a trashed accordion:
TALLINN
Between 5-9 March, students of the EKA (Taavi Suisalu, Evi Pärn, Lilli Tölp, Aleksander Sprohgis) learned to make their own primitive noise synthesizers with me. Lilli made this short video capturing the essence of the final presentation plus a tiny bit of my solo set.
Like the previous Neanderthal Electronics presentation, back when Ptarmigan was still located in Helsinki, this one was a complete success. Thanks to Raivo Kelomees and John Fail for organizing the workshop and presentation, respectively. Any account of my Estonian trip would be woefully incomplete without mentioning Timo Toots and Marika Agu and their Sunday-afternoon tour of the Architectural Wonders of Tartu. Aitäh!
Live set @ Taka, Riga, March 16th, 2012. Derek Holzer: analog synthesizer, soundbox, found objects. Jelena Glazova: voice, laptop.
Parts 1 and 2 plus some studio sessions can be found at Holzer vs Glazova.
Thanks to Sandis Baumanis [ULVE Agency] for organization and photos, Jēkabs Nīmanis for recording, Edgars Rubenis for the mixer and Olesja for the lovely smile.
Unfortunately, the only souvenir that RISEBA, the school I was teaching at, left me was a headache. Typical Latvian new-capitalist neoliberals, they seemed to delight in playing ridiculous games over even the smallest amount of money, making them little better than con-artists. The result: I worked twice as many hours this workshop as last year, for the same amount of pay. Count your fingers after you shake hands with people like these…
On that note…
People like these business-school asswipes make me sicker than ever of this constant freelancing life. I have been actively searching for more constant employment teaching at an art, music or design school lately. If any of my dear readers have tips, I would gladly hear them. In some ways, I am beyond caring where such a job might be at this point…
On the other hand, spring has arrived in Berlin and I have very little travel coming up. While that may make the coming months a bit lean and hungry, I hope to use the time to catch up on projects I have promised people, including two cassette releases and a film soundtrack, as well as building some new soundbox-type instruments for sale. Wish me luck!
