Emergent Bird Music
"The Barbican today unveiled its latest art commission, which has seen one of its gallery spaces transformed into a walk-through aviary by French artist Céleste Boursier-Mougenot. He has strategically placed plugged in electric guitars as perches and cymbals containing water and seeds as feeders. As the birds fly around and land on the instruments, or even wipe their beaks on the strings, the visitor will hear the amplified results."
The "concept" in this kind of art-piece seldom interests me. If someone makes a piece involving music (or what they call music) then it has to sound good, or at least interesting. This guy seems to have succeeded. You can hear the audio here: http://www.guardian.co.uk/culture/interactive/2010/feb/26/culture-barbic...
