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.

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.
Genosong is an improvising ensemble with live sampling. It incorporates live electronics as an augmentation of traditional acoustic instruments in an improvisational context through live sampling alone: no pre-recorded sounds or synthesis methods are used. A natural and organic electroacoustic soundscape is produced that acts as an additional voice in the ensemble; this results in further development of the musical material by the players that is then also sampled. The creation of this feedback allows for extremely interesting emergent behaviour where smooth and gradual processes are juxtaposed against abrupt and chaotic changes.
