Playing MIDI guitar into a computer, Boomerang loop pedal and a Metasonix module, Robert's "Duchamp Examination #10" dissects, examines and re-produces a precomposed (but not prerecorded) piece through a combination of analog and digital mastication and redigestion, in real-time solo performance. Duchamp might have said "Bob chews his cud". Robert explores the source piece "If Duchamp Drew Beautifully".
