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.

Último Esfuerzo Industrial III (2015)

At the exhibition A.N.T. Technological art and natures, 18-09-2015 — 14-11-2015, Galería Punto, Valencia, we premiered a new version of the work, much more intimate and mysterious than earlier versions with a more open and less predictable computer program and audio levels that only add a just a subtle extra to the sounds that produce the motors without amplification. The other artists of the exhibition:

José Antonio Orts, Hugo Martínez-Tormo, Rafael Lozano-Hemmer, Solimán López y Enrique Radigales.

Sound recordings:

At the concerts in Bilbao the sound was being amplified only with the four bass amps while in Murcia and Madrid these sounds were sent to a mixer from the line outputs of the amps and then distributed with a bigger sound system with more spatial and dynamic control. The first 2:30 of this recording comes from Murcia, while the following 10 minutes is an excerpt from  Madrid. The concerts lasted 30 minutes.

Último Esfuerzo Industrial I (2012)

Our work Último Esfuerzo Rural (“Last Rural Effort”) was premiered in Valencia at the Ensems festival of contemporary music in May 2004. It is composed of two complementary installations. Together these produce a poetical ode dedicated to rural life and its people with an independent and creative state of mind that is disappearing in our globalised world. At the time we combined three periods in the project: The rural, industrial and computerized eras. Eight years later, it was about time to dedicate a work to the mechanical and analogue era, before nobody remembers how real things work and interact.

Último Esfuerzo Industrial I is a simple and effective work. It consists of three electric motors mounted on a small metal table, three frequency controllers, three contact microphones and three bass guitar amps that amplify the signals captured by the mikes. The motor speeds are controlled manually with analogue control units.

Último Esfuerzo Industrial

Its sound is extremely dynamic with frequencies parting from humming basses and pleasant mids up to acrid trebles.

Último Esfuerzo Industrial was performed as a concert  at the festival Nits d´Aielo i Art , Valencia, 14-03-2012. More info about the festival at
