In cooperation with Boston Cyberarts, If All Those Able Minds Could Be Set Free represents the Demoscene, a diverse computer art subculture focused on demos, or real-time rendered audiovisual demonstrations of coding, musical and artistic prowess. While Chiptunes are live performances that include the use of traditional acoustic and electronic instruments, alongside Gameboys, Commodores and Amigas, as well as more modern computational devices like palmtop computers. Featured artists include Br1ght Pr1mate, combining the forces of indie-scene alum Lydia Marsala and James Therrien (Fugitive Kind), Arkbit and the Attic Bat plus Don Miller (NO CARRIER).
