Virus #1
Virus #2

Virus #3.0
Composition for live generated electronic resonating body
strings, woodwind and brass instruments, percussion sets

Sound engineer: Peter Venus
Commissioned by RSO Vienna

The live generated electronic resonating body is the host to which the sounds of the instruments attach and adapt, they penetrate into it and use it for their replication. At first the body is immune, but during the course of the piece the body stops resisting, takes in the sounds of the string instruments, and allows the viruses to multiply freely. It is a struggle and synthesis between two resonating bodies. Together they stay alive.

The Virus #* series was inspired by one of those rare moments of happiness. I had just heard Terretektorh by Iannis Xenakis performed by the RSO at the Wien Modern Festival 2009 and came away absolutely high! And yet I felt there was something missing – electronic sounds and the way they move through the room in a somehow different way. I was buzzing with questions, ideas for experiments. I think in terms of bodies, my field is electronics. So I wondered HOW can I communicate with a resonating body such as an orchestra? I opted for the language most familiar to me – live generated electronics – listening. Not sugar sprinkles or mere effects, ¬absoluteness – the score.

This image of a virus has emerged from inside of me.

I approached this challenge slowly. Virus #1 involves individual groups of instruments, Virus #2 a combination of two groups of instruments, Virus #3 a synthesis of all groups of instruments I have worked with thus far.

23 instruments, 15 voices, 75 oscillators, 75 meters. 24 pairs of ears open themselves to a feedback loop. I – the electronics – the host – the recursive control unit – a complex machine.

Both bodies are audible. The virus series is an expedition into acoustic perception, a sounding of the responses of our brains in the span of milliseconds, a plea for the precise acoustic moment.
And what do you hear?
