Sweeney Todd has been shown over and over to be open to all sorts of approaches and interpretations – large or small scale, darkly humorous or pure horror, literally visualized or symbolically represented. With the touring production of John Doyle's take on the piece, we now have an interpretation within an interpretation. While the 2005 Broadway revival of Doyle's actors-as-orchestra set in a modern-day-madhouse was unrelentingly dark and intense, the production now at Chicago's Cadillac Palace Theatre through May 4th is more in the black humor mode. For those who have seen Doyle's Sweeney Todd and Company and have become accustomed to seeing actors double as the orchestra, it's appropriate enough to shift focus to character interpretation, particularly given the distinctive performers in this cast.
