  print
 
saturday january 10, 2009 – sunday january 11, 2009
OKNO HQ
 


We'll connect with friends in Bratislava for a bricolage session in hydrophonics. Underwater recordings are excellent for soundscapes and communication with your favorite submarine.
Useful tools would be: microphones, computer and condoms.

HYDROPHONE WORKSHOP / HYDROFONICK? DIELŇA

Saturday 10.01.2009
Sunday 11.01.2009
everyday 13.00-18.00
Place: A4 klub, Bratislava
Contact xgz -> societyofalgorithm.org

For two days G?van Bel?, and Tobi?? Potočn?, are inviting artists
to make their own hydrophones (underwater microphones). We will try to
make the 3 types - condom protected, isolated piezos, and oiltank
condensers. Then move to recording with them in the Dunaj, the frozen
lakes, the swimming pools, your bathroom and toilet, your uncle's
fishtank... The idea is to make underwater field recordings during a
week, and upload them on this site. But additionally, we want to look
into treating the sound material, and making interesting shared pieces
with it. On Art's Birthday, these will be used for an evening long
connected internet concert between Bratislava, Tokyo, Brussels, Praha,
Budapest, and elsewhere... So bring your favorite recorder device (and
possibly computer). For people staying at home and building it there,
we provide a chat channel and stream from here.
