Events 2017

In the course of 2017 we have shown the project Último Esfuerzo Rural III-V five times in different versions and contexts.

Video by Tanja Busking about the artist residency at iii the Hague during October 2017 and the exhibition of Último Esfuerzo Rural V at the sound art exhibition at Kruithuis – STOK, during the festival November Music, 5-12 November 2017. Video and exhibition were commissioned by iii.

Último Esfuerzo Rural III at the art fair justMAD, Madrid, Feb 21-26, 2017.

Último Esfuerzo Rural III (2017) is the third project of a series of works inspired by the area we live in, the rural interior of Valencia. We are not trying to romanticize rural life; rather our work is inspired by the creativity and strength of the individuals, so typical of isolated rural communities: the individual him or herself looks for simple, but creative and playful solutions to the problems that occur in the world surrounding them (with sweat, strength and courage). Recently we started to collect antiquated metal objects from our area. The objects include large pans for boiling onions and funnels made of tin plate, way back used in the production of sausages, and ewers once made for measuring quantities of olive oil. They are brought back to life by tiny air-driven industrial vibrators. Once brought into resonance our objects recover their forgotten value by producing mysterious, hypnotic sounds: a process whereby the potential energy of once meaningful, but now dead objects, is being transformed into a spiritual experience, by stimulating their resonant frequencies in an unusually unpredictable and vivid manner. A listener can choose his own perspective in the sonic environment created by the installation by moving around below the objects. Also inside of the objects unpredictable behaviour takes place: Normally this type of vibrator is firmly mounted with bolts, whereas we attach one or two metal springs below each. This enables the vibrators to move around inside their object, propelled by their own vibration, causing different timbres and sound volumes. Each object also influences the behaviour of the others: Because all the vibrators share the air from the same limited source the activity of already sounding objects diminishes when others come to live, resulting in a fragile and complex sonic system, unpredictable in its smallest detail. In future versions we will increase the number of objects, and possibly choose objects, related to a specific site or country.

Special thanks to Günter Geiger for his assistance in the development of software and to Almazara Hnos Martínez Zaballos and Pepa and Vicenta Torralba for their ewers and pans.

Último Esfuerzo Industrial II (2014)

Último Esfuerzo Industrial II,  Chelva, October 2014

Último Esfuerzo Industrial II, Chelva, October 2014


Último Esfuerzo Industrial II consists of four electric motors, four frequency controllers, four contact microphones and four bass guitar amps that amplify the signals captured by the mics. The motors are mounted on ancient moulds for the production of cast iron from Puerto de Sagunto, an industrial town north of Valencia, founded at the beginning of the 20th century. These wooden moulds are not just pedestals they also function as sound chamber for the microphones. Together with the old second-hand motors with reduction gear and cogwheels they evoke the aesthetics and dreams of the futurist movement of an age ago. At that time, sound design and control were very limited, but now contemporary laptop performers enjoy almost infinite sonic possibilities. Último Esfuerzo Industrial II builds a bridge between these two eras with simple and direct means. The contact microphones do not only capture mechanical noise, but also the electromagnetic interferences caused by the pulse width modulation that is used for the speed control of the motors. The motors are being used as variable pulse width oscillators that produce a more dynamic and complex sound spectrum than the oscillators normally used in analogue electronic music. Their frequencies are being controlled with a computer when shown as autonomous installation and manually with analogue control units in concerts. At the MEM festival in Bilbao, November 2014, the work was exhibited during three weeks. At the opening concert only the four bass amps were used for amplification. In January 2015 two concerts were given in Murcia and Madrid. Here the sounds were sent to a mixer from the line outputs of the amps and then distributed with a large sound system with more spatial and dynamic control: an intense and immersive experience lasting 30 minutes. In future performances the work may be expanded to 5 or 6 motors.


Special thanks to FCV Patrimonio Industrial Puerto de Sagunto for providing us with cast iron moulds from their collection.

Mirlitones at ICMC / Totally Huge New Music Festival, Perth, Australia, 2013


During 14-18 August, 2013 Mirlitones was shown as part of the ICMC 2013 and the Totally Huge New Music Festival at the Kidogo Art Institute, Fremantle, Australia. For the occasion we made a new computer program based on data taken from seven planets. The length of the pipes is related to the diameter of these planets and the elapse in time of the dynamics for each pipe is deduced from day and night cycles. Each pipe is treated differently  resulting in a slow, hypnotizing, ever changing sound mix. A new phase in the development of the work.

Another, practical novelty is that the pipes were bought in Australia while all other essential materials were brought in the plane as personal luggage. A formula that can be performed worldwide with little transport costs.

August 17 bass clarinet player Krista Martynes improvised together with the installation after a short introduction on the work by Peter Bosch.


Sound recordings: (play/pause at the left part of the bars)

The 1st track is a recording from the centre of the space when working as an autonomous installation, the 2nd is an excerpt of a recording made by Johannes S. Sistermanns of the live improvisation.

Wilberforces is a new work within our long series of vibratory projects. The title refers directly to a phenomenon from science, the Wilberforce Pendulum. This pendulum is nothing more than a hung metal spring with below it a central weight plus eccentric weights for calibration. The secret of the system lies in conceiving a calibration in such a way that the resonant frequencies of vertical movement and rotation of a spring are so near to each other that once set in motion its movement can change gradually from vertical motion into rotation and vice-versa without adding energy from an external source. It is an example of a coupled mechanical oscillator, often used as a demonstration in physics education.

In Wilberforces three long springs are used for generating video and audio data. The springs have a length of around six meters, a size normally not found in physics laboratories and resulting in spectacular large and slow movements. Each spring is hung from above and attached to a pneumatic actuator that sporadically adds energy to the system. Below one of the springs hangs a video camera and microphone, below the other two hang tiny loudspeakers. Signals from the moving camera, mike and speakers provide the basic material for the sound and images produced by the work, obviously influenced by everything occurring in and around the FACT Atrium. The irregular motion of the springs can be tracked and experienced through a real time projection of further processed sound and image within a purpose-built dark space at the rear of the building.

Mirlitones and Krachtgever at “Kunst Werkt”, Dordtyart, 2012

A big version of Mirlitones was commissioned by DordtYart, Dordrecht and shown in their space at the exhibition “Kunst Werkt” during April-September 2012 together with Krachtgever (1994-98). More info at

Mirlitones (2012)

Mirlitones was commissioned by DordtYart, Dordrecht, Netherlands. The title refers to a primitive instrument that has appeared in a multitude of forms in various parts of the world. All these instruments exist of a hollow form with a membrane mounted that can be brought into vibration by blowing or singing. The best-known member of the family is the kazoo used until present times in pop music.

The point of departure for the work was the spectacular noise produced by children with minuscule plastic mirlitons in the cavalcade of the Funeral of the Sardine, the final act of the biggest fiesta in the Spanish town Murcia.

In 2004 we built giant lions roars for Último Esfuerzo Rural where we created a new context for age-old instruments. Also the Mirlitones are much bigger than their predecessors and produce a world of sounds little known in musical practice. The installation exists of suspended vertical pipes, one to three meters long, equipped with a vibrating membrane at the upper side. The air used to bring the membranes into vibration comes from a compressor and a web of tubes and taps controlled by a computer. Small fluctuations in the air pressure cause subtle changes in the sound, composed of many ultra-low frequencies, harmonics and phenomena like beats and combination tones that arise from simultaneously sounding pipes. Because all the pipes share the air from the same limited source they also influence each other resulting in a fragile and complex sonorous system, unpredictable up to the smallest detail.
