OstraconOstracon is John Keston on electronics and Graham O'Brien on drums. The duo performs generative, improvisational compositions using John Keston's custom software, the GMS (Gestural Music Sequencer), that converts video input into musical phrases.

Keston captures, layers, loops and processes melodic segments in real-time out of the stream of notes created by his gestural input, tailored with probability distribution algorithms. O'Brien accompanies these angular, electronic structures, with dynamic playing that, at times, verges on the chaotic.
