Ostracon 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.
John Keston is a musician, composer, and sound artist exploring the
synesthetic relationships between auditory and optical landscapes. He is also
interested in evoking stochastic behaviors in compositional structures by
translating visual or gestural input into sound. One example of how John is doing
this is with the Gestural Music Sequencer (GMS). The GMS is an application that
John developed in Processing.org that analyzes video input and converts it into a
sequence of musical information in real-time.
Originally from the United Kingdom, John is currently based in Minneapolis,
Minnesota where he is an instructor in interactive media at the Art Institutes
Minnesota. His work involves composition, experimental software development,
music and sound art. He founded the sound design resource, AudioCookbook.org,
where you will find more documentation for his projects and research.
On AudioCookbook John selects a few examples of work that he has produced
recently. This will include audio works found under sound, custom built
applications and digital art under images, and music releases under discography.
Graham O'Brien is a drummer, producer and composer. He has produced and recorded
music for artists and groups around the Twin Cities and nationally, including
Eyedea, Sadistik, Kristoff Krane, No Bird Sing, Moon & Pollution, Carnage, Kill
the Vultures, and officially released remixes with Halloween, Alaska, Sadistik,
Guante and Sole. In 2011 Graham released his solo debut as a producer & composer
entitled "Live Drums". It was warmly received and released on NoEcho Records out
of the UK.
