Here is a little installation from the Out of the Cage day at Trinity Laban Conservatoire last week at the Old Naval College site in Greenwich. The day was a centenary celebration of John Cage comprising 10 hours of simultaneous concerts, installations and happenings. My contribution consisted of a small bird cage hung high in a stairwell. Inside is a small speaker playing something that sounds suspiciously like birdsong. In fact it is a single sine-wave partial isolated from a recording of Cage reading his famous Lecture on Nothing. The piece uses similar partial tracking technology to my Exploded Sound project and if you listen very carefully you can hear Cage in the background.
