DELILAH TOO at CTM Festival Berlin

Posted in Announcement on January 13th, 2015 by admin

My vocoder-based sound installation DELILAH TOO will open at the CTM Festival, in the Kunstraum Bethanien on 23 JAN 2015, and run until 22 FEB.

I am looking for a number of volunteers to speak, read or sing texts in any language you choose, as well as attempt to communicate with installation visitors (hopefully in a language they do understand) during the entire month of the festival. In the spirit of Alvin Lucier’s “North American Time Capsule”, you could consider these texts as transmissions to other beings in space about what life on Earth is like for you…

I hope that a number of people can take one or two one-hour long slots, and I will try to make a small gathering with snacks/drinks sometime during the festival for people who help out.

You can find a short overview of the project here:

Please contact me by email at MACUMBISTA at the domain GMAIL dot COM with the subject line “volunteer” and I will send more information and a link to the sign-up sheet.

Many thanks!!!! D.

Edith-Russ-Haus Grant 2014

Posted in Announcement on March 31st, 2014 by admin

Today I was informed that my application for a grant from the Foundation of Lower Saxony at the Edith-Russ-Haus 2014 was selected by the jury! I will be working on a vocoder-based sound art installation during the second half of 2014. Thanks to the jury for their kind support!

Derek Holzer, Delilah Too

With his project DELILAH TOO, the Berlin-based American sound artist Derek Holzer conducts media archeological research toward the development of a language cryptography instrument on the basis of a vocoder. This device from the history of electronic music constitutes the foundation for a multipart sound installation. It enables visitors to transmit encrypted conversations from one private space to another, where the listener can then decrypt them. The voices modulated in this way produce an abstract electronic spatial sound that can be perceived by all of the visitors in the surrounding public space.

With his experimental sound art project, Derek Holzer not only transforms an instrument from the early history of electronic music for current use in producing analogue compositions, he also creates an artistic transmission of the current debate concerning the protection of the personal and the boundaries of the public sphere. The jury was persuaded in particular by Holzer’s in-depth research on the history of electronic sound generation and his scheme for its artistic implementation in a do-it-yourself process as well as by his socio-political approach, which not lastly find expression in his eponymous reference to Alan Turing’s secure speech device Delilah.

LAK Festival Copenhagen Documentation

Posted in Documentation on September 18th, 2012 by admin

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.

Regnskov 2012 in Copenhagen and Aarhus

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.

You can download a PDF of information about the project here:

Wolf-Tone Box + Helsinki Report

Posted in Documentation on June 9th, 2012 by admin

Wolf-Tone Box

Wolf-Tone Box, Derek Holzer 2012. Microphone, speaker, voice-changing circuit, antique wooden box. Created for the “Invisible Time” show at MUU Gallery, Helsinki, 8-21 June 2012. For sale, inquire here.

Helsinki Report

The MUU opening went very nice, a good crew running the space with a nice selection of artists. My favorite moment was when a little girl, aged four and very shy at first, quickly learned how to play one of the SoundBoxes better than me! I brought 7 sound boxes in total, which remain available for visitors to experiment with for the next two weeks, as well as screened the nonlinearity and cryptography videos. Installation views below.

The travel was a bit rough, however. I’d been a bit sick the days before the flight, and when the plane landed in Helsinki, my left ear felt like it was going to explode. I asked a doctor, who said I might rupture my eardrum if I flew, and weighed the options of a trip by boat, bus and train back to Berlin. Things seemed best to use the airplane ticket the gallery already paid for, rather than spend money and time I don’t have on a 30+ hour overland journey. But the four hours I spent swallowing hard to keep my eardrum from bursting were pretty nerve-wracking…

Moral of the story: don’t fly with a flu. Trust me.

Video: Regenwald2011 at Club Transmediale

Posted in Documentation on March 10th, 2011 by admin

Regenwald2011 at Club Transmediale from macumbista on Vimeo.

By Derek Holzer & Mads Bech Paluszewski

Regenwald 2011 was a contemporary re-interpretation of David Tudor’s series of compositions from the 1970’s entitled “Rainforest”. It used different types of sonic transducers to play sounds through a series of resonant metal objects suspended in the space. Additionally, two 8×8 matrix mixers allowed the sound from any of the objects or performers to be sent to any other node in the network, making the whole piece an experiment in generative chaos.

Regenwald 2011 was developed prior to the festival in a workshop format over a period of five days. The opening night presentation featured a live session with the system,
while the installation running during the week employed recordings made with the system. The audience was free to move around the performance space, engage in conversations and explore the sonic objects, thus adding new life to the rainforest.

Regenwald 2011 was coordinated by Derek Holzer and Mads Bech Paluszewski, and was a joint production of CTM.11 and Tuned City / DOCK e.V.

Regenwald 2011 @ Club Transmediale

Posted in Announcement on December 23rd, 2010 by admin

Regenwald 2011: a workshop/installation/performance in the spirit of David Tudor

with Derek Holzer (USA/DE) & Mads Bech Paluszewski (DK)


Regenwald 2011 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 various resonant objects in the performance space, as well as through architectural features of the space itself. Additionally, an 8×8 matrix mixer allows the sound from any of the objects to be sent to any of the performers, making the whole piece an experiment in generative chaos.

Regenwald 2011 will be developed in a workshop format with up to 8 participants over a period of several days. The resulting work should shift between relatively static installation-like moments and performative sections where the artists seek new relationships with the objects and each other. The audience is free to move around the performance space, engage in conversations and explore the resonant objects, thus adding new life to the rainforest.

A opening night presentation will introduce the concept of Regenwald 2011 and the context of “Schematic as Score” as seen in the works of both David Tudor and John Cage.


A rough schematic of a previous transducer system (Regenskog 2010) can be seen here:
