In his piece Portrait of a Ghost Drummer, Polish artist Bartek Szlachcic uses motion-capture and other technology to track then display the intricate choreography of a musician's hands hammering out a drum solo.
The audiovisual artist explains:
The drum sticks are the extensions of drummer's hands like a brush is an extension of the painter's hand. Motion-captured movements become a visual map over a time revealing fragile rhythm structures and invisible notations behind energetic instrumental solo. 'Portrait of a Ghost Drummer' expands the understanding of drummers activity from purely auditory experience to spontaneous visual performance. From technical point of view motion trajectory was captured on Vicon MX system and raw CSV files were translated into visual language in 3d environment Cinema4D.
