Three live performances of collaborative electroacoustic compositions from 2007-08, recorded in London, Brisbane and Antwerp, each exploring different points of contact between precomposed structures and spontaneous invention: a duo adrift (in memory of Paul Rutherford) with pianist Sarah Nicolls, a nonet codex IX (in memory of Mauricio Kagel) with the ELISION ensemble, and a 17-piece group with Ensemble Champ d'Action realising codex VII (to Vinko Globokar).
