robotcowboy is a performance project consisting of a wearable computer system and various peripheral devices which enable a single performer to become a mobile, technological “one-man band” free to roam the stage, the street, and the world. It is both an homage to the “one-man band” tradition and an exploration into a post-digital renewal of embodiment and physical instrumentality in electronic musical instruments. The system is built with low-cost in mind and utilizes readily-available hardware and free, open source software in order to make the concept feasible to the everyday computer performer who wishes to step out from behind his screen. It is hoped that the concept of a wearable music computer can one day become as ubiquitous as that of laptop musician in a return to the fragility and excitement of live music.
