For those unfamiliar with the 1886 original story of Jekyll and Hyde - - it is a tale of the strange case of Dr. Henry Jekyll, a fictional 19th century London physician who decides to experiment on himself using what might be described as psychotropic drugs.  In doing so he unleashes his own demon in the person of his alter ego Mr. Hyde. This excellent musical version is presented by Kokandy Productions at the Chopin Theatre in Chicago.
