This performance is the premiere of Donald D. Craig’s guitar duet with Aural Fauna, a family of unknown organisms imagined by AI. Aural Fauna specimen’s forms and sounds are generated by machine learning algorithms that were developed by a team of artists and machine learning researchers including Craig and his long-time collaborator Eunsu Kang. During this improvised duet, Craig and eight fauna entities listen and respond to each other by changing pitches or the tempo or adding additional parts or harmony.
