		Sine Field - Jason Kahn (Zurich/CH) minimal percussion + live computer processing The psycho acoustic properties of high frequency sine waves are such that any slight movement of the listener's head will produce a radical change in the perception of the sound. The idea behind the installation Sine Field is to activate a space with sound bordering on the physical limits of perception. On entering the installation space the listener will perceive a net of finely oscillating frequencies-a part of the oscillations resulting from the shifting in-and-out of phase between the different sine waves; another part resulting from the listener's movement in the space and the gradual shift of sine waves from speaker to speaker. The nature of the high frequency sine waves and the shifting speaker diffusion will result in a subtle yet unmistakeable manipulation of the listener's spatial orientation. Sine Field addresses the questions: where does the perception of sound beginand how much of this perception occurs on a strictly physical as opposed to a psycho acoustic level; and how is our spatial orientation determined in a field of sound where the acoustic reference points are always changing? jason kahn moved from los angeles to berlin in 1990. he has given concerts with, among others, sainkho namtchylak, david moss, evan parker, christian marclay, günter müller, dieb13, erik m, voice crack, steve roden, kevin drumm, john hudak, bhob rhainey, greg kelley....over several trips to japan kahn has performed with otomo yoshihide, sachiko m, taku sugimoto, tetuzi akiyama, utah kawasaki, uchihashi kazuhisa and koji asano. in 1997 kahn formed the project "repeat" with no-input mixing board player toshimaru nakamura. while living in berlin kahn was from 1994-99 a member of american composer arnold dreyblatt's ensemble «the orchestra of excited strings.» kahn has also composed music for theater, dance and done sound installations. he currently lives in zürich, switzerland. > http://www.cut.fm Kotra (UKR) + Akuvido (visuals/UKR/D) performance Kotra is a solo project of Ukrainian artist Dmitro Fedorenko from Kiev. He is a member of the post-industrial band Zet and also known for his sound-design for the video works and interactive projects of Akuvido. His music can best be described as extremely precise digital sound manipulation - a so far unheard approach to glitch music with a touch of minimal techno and post industrial clicks and cuts. Definitely obscure and bizarre, abstract constructivism, noisy but with sometimes even funky stumbling beats. Kotra releases on the Ukrainian Nexsound label run by Andrey Kiritchenko. > www.nexsound.org > www.akuvido.de
