THE SOUND OF THE CARCERI explores the deep relationship between music and architecture through a high-tech 'virtual confrontation' between Bach and his contemporary, the architect Giovanni Battista Piranesi. Using a striking visual style, director Francois Girard ('The Red Violin' and 'Thirty-Two Short Films about Glenn Gould') places Yo-Yo Ma within a series of computer-generated, three-dimensional recreations of Piranesi's well-known prison etchings. Through Yo-Yo Ma's and music producer Steven Epstein's struggle to recreate and interact with the imaginary space that Ma performs in, the film examines the complexity of illusion, of representation and reality.
