nonlinearity II from macumbista on Vimeo.

Continued studies in nonlinearity, this time using cross-coupled oscillators, smooth/stepped generators and random voltages from the Wogglebug run through a series of Buchla Low Pass Gates and plotted on the oscilloscope. Recorded 14.09.11 at the Danish Institute for Electro/acoustic Music, Aarhus. Reminiscent of Jackson Pollock’s action paintings, mid-century Modernism and a time before the information machines took over. A sketch quickly realized in the dark with improvised tripod and bad, in-camera microphone. To be expanded. Watch with the lights off.

Several years ago, I largely abandoned the digital sound world to spend time building a modular analog synthesizer which reinterprets and hybridizes the forms and functions of the famous Serge and Buchla systems of the 1970s. In my largely improvisational performances, I summon the chaotic, generative powers of this machine to explore the physical affects of volume, frequency and complexity within a given space. For fans of Maryanne Amacher, Bernard Parmegiani, Eliane Radigue and Slayer.

Regnskog 2011//Full Pull 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 performers to be sent to any of the objects, making the whole space a an orchestra of resonant voices to be played.

Regnskog 2011//Full Pull 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.

On Friday 30 Sept 2011 at 20.00, Regnskog 2011//Full Pull will be presented in a concert situation at Stapelbäddsparken, Stapelbäddsgatan 3 Malmö SE. The following afternoon, Saturday 01 Oct 2011, it can be seen as an installation between the hours of 12.00-19.00.

Regnskog 2011//Full Pull is coordinated by Derek Holzer and Mads Bech Paluszewski for the Full Pull Festival.

I finished this in a beautiful last-minute rush before packing the studio for my move to Denmark. Behind this panel live two members of the Wogglebug species: random voltage generators based on the famous Buchla Source of Uncertainty, coupled with a very bizarre ring-modulated tone oscillator. The only thing which could possibly be more fun than having one source of uncertain electricity is having two of them. When they talk together, they make each other even more uncertain, like two nervous nerds in the kitchen at a party. Samples later, I’m still building up my studio at the Music Conservatory.
