Sunday Synth Jam: This video captures a psychedelic hypnotronica improvisation by Ostracon, featuringJohn 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.”
