Russell Haswell and Florian Hecker are both prolific as solo artists, each with numerous collaborations with other artists to their respective credits, Haswell also having been a contributor to and touring member of Consumer Electronics. The UPIC Diffusion Sessions are a long-running collaborative project which began in the early 2000s, exploring Iannis Xenakis’ UPIC system as the sole instrument.
As the accompanying notes outline, ‘The UPIC is a computer music system that generates sound from visual input. The original intention of the system developed by Xenakis was to make a utopian tool for producing new sounds accessible to all, independent of formal training. One can locate footage of Xenakis and a group of children making drawings for the system in the 70’s.’ They continue, ‘The duo set off experimenting with a diverse array of hand-drawn images to feed the UPIC system including news photographs of disasters and atrocities, “food porn” through to depictions of the natural world and microscopic images of molecular structures (including ‘the blackest ever black’). The resulting eccentric audio from these images is claimed by the artists to heighten synaesthesia and is as mysterious as it is baffling.
I suppose the potential outputs for the UPIC are as infinite as the inputs, and this alone makes for a fascinating project, and the results here are, indeed, mysterious and baffling. The recording from this session is represented by a single track, just over half an hour in length.
Immediately, trilling oscillator tones rise in pitch – and keep rising, until you feel the pressure build inside your skull. There are glitching spasms of sound which flash across like subliminal messages. The pressure drops and the siren wails fade out, before scuttering blasts of seemingly random noise collage and intersect across one another, buzzing and fizzing, humming and thrumming… the forms move quickly, and shift from dark to light, hard to soft instantaneously. Shimmering sprays of abstract sound burst like fireworks, short interludes of harsh noise wall, microtonal bubbles and ZX Spectrum like babbles and bleeps all intersect or pass within mere seconds of one another. It is, very much, a sonic collage, the audio equivalent of William Burroughs’ cut-ups, an aural articulation of the simultaneity of experience of life in the world. Burroughs’ contention was that linear narrative is wholly inadequate when it comes to representing the real-world, real-time lived experience, whereby overheard conversations, snippets of TV and radio, and all the rest, not to mention our thoughts and internal monologues, overlap, and to present them sequentially is not true to life.
Leaping disjointedly from one fragment to the next at a bewilderingly rapid pace, listening to this is rather like the way the mind, and often conversations, skip from topic to topic without ever seeing any single train of thought to a defined conclusion, bouncing hither and thither in response to triggers and associations which often seem to bear no logic whatsoever.
There are thick, farting sounds, buzzes like giant hornets, choruses of angry bees, weird sonic mists and transcendental illuminations… of course, these are all conjured in the mind in response to these strange, sometimes otherworldly, sci-fi sounds, part BBC Radiophonic Workshop, part tinnitus and nightmare of imagination. Unpredictable isn’t even half of it as alien engines and spurs of 80s laser guns crossfire against earthworks, roaring jets, explosive robotics, skin-crawling doom drone, whispers and whistles, proto-industrial throbs…it’s a relentless blizzard of sound.
‘Experimental’ has become something of a catch-all for music that draws on eclectic elements or perhaps incorporates a certain randomness: this, however, is truly experimental, given that there is no way of knowing how the programme will interpret the input provided. And as much as the output involves oscillatory drones and the kind of synthy sounds associated with analogue, and with woozy, warping tape experiments, it evokes the drones of collapsing organs, wild sampling and everything else your brain could possibly conjure.
At once exhilarating and exhausting, UPIC Diffusion Session #23 is… an experience.
