The Korean and Japanese languages contain many onomatopoeia to describe phenomena which produce no sound e.g. how things look or feel and emotions. This mixed-media installation is based on this practice of “sound symbolism” of silent phenomena.

Construction in Zhuangzi

Audiovisual work based on a modified Lorenz dynamical system.

Construction in Zhuangzi is a live “audiovisualisation”: the simultaneous sonification and visualisation of the same process and data in real-time. It is based on a modified Lorenz dynamical system, a three-dimensional model of convection that is non-linear and chaotic and has sensitive dependence on initial conditions or the “butterfly effect”.

A performance consists of an attempt at understanding and controlling the mechanisms of the near-autonomous generative system through an improvisation involving the modifications of the parameters of the Lorenz. Moments of human intervention are indicated by a colour inversion and an audio click. Lorenz stated that the equations do not produce realistic representations at large values of the parameters of the equations. In the work, these parameters are taken to beyond their original real-world limits in order to explore a speculative world. An appropriately machinic or post-human sensibility is evoked through a digital noise/glitch presentation of the emergent phenomena.

The work is featured in the Electronic Music volume of the Cambridge Introductions to Music series. A fixed-media version of the work was awarded 2nd prize at the Fresh Minds Festival, TX, and was part of the official selection for Videomedeja – 16th International Video Festival and MADATAC 04 Contemporary New Media Audio-Visual Arts Festival.

Ryo Ikeshiro new generative audiovisual work

Manabu Shimada glitched field recordings

The earthquake and tsunami of 11 March in Japan and subsequent after shocks have claimed over 15,000 lives, with 8,700 missing. Over 270,000 homes suffered damage, and almost 150,000 homes were completely or partially destroyed. Two months on, more than 100,000 are still living in evacuation shelters. The international response has certainly helped in starting the relief operation, but there is still much to be done. Any donations will be gratefully received.

The series will present two performances of each work with a talk/discussion in between. Program notes or explanations heard prior to experiencing a piece of music can sometimes affect how we listen in an unnatural way. On the other hand, they can give us useful pointers in appreciating music that might otherwise be difficult. Having two performances is a way of hopefully resolving these issues, with the first listening being unspoilt and the second more informed.

Please join us at any point in the evening. For the discussion, see links for blurbs and related articles. With kind support from EMS and SPR.

Construction in Self

Construction in Self is a generative work based on the Lorenz dynamical system. It has sensitive dependence on initial conditions, giving rise to what is commonly known as the “butterfly effect”. Its generative form is suggested by this property and the work takes an input prior to performance as initial conditions from which a different piece is produced each time. A diverse variety of behaviours are observed ranging from periodicity to chaos that yield interesting results as signal, control and meta data, suggesting a self-similar microcosm that is complex yet deterministic which can be replicated from the same initial input. The title is a reference to John Cage’s Construction in Metal series (1939-42) in which simple sequences of numbers – referred to as “rhythmic structures” – are used as a basis for structures at different time-scales.

Construction in Self has been performed at noise=noise the Basement Series 2009, London, ICMC 2010, New York, CONTEMPORANEA 2011 ‘Japan 2011′ Festival di Nuova Musica, Udine and 希/日 GR/JP at Het Nutshuis, Den Haag.

David Tudor’s Rainforest IV

This slideshow requires JavaScript.

Tudor’s seminal work from the 1970s is a template for what is now called sound art today. It involves resonating sound sculptures, audience interactivity, collaboration, use of found objects and feedback loops and networks.

The group installation/performance took place in Area 10 Project Space in Peckham. It was a former Whitten’s warehouse which was used as an event space for several years before being closed for demolition and subsequent redevelopment.

All the material used for the sound sculptures were found within the vicinity of Area 10 which included remains from the timber warehouse, discarded objects from building and development sites and general junk. The event took place within the backdrop of the changing landscape of Peckham and the tide of gentrification that was to follow.
