Martin Bartlett should be a familiar name. As well as working with a who's who of electronic music, he was an inspiring and original thinker, composer, performer and organiser. His music is distinctive for its warmth and fleshiness, for taking joy from the incidental and anecdotal, and it remains a characterful counterpoint to much contemporary electronic music. It is his preoccupation with building aleatoric elements into electronic music that distinguishes his work, and he devised elegant and open interactions for instrumental performers and computer-controlled synthesizers. This included building his own electronic devices, and extensive work on the Buchla 400.
