The tragedy of bad leadership is the theme of William Shakespeare's historical play "Richard II," given a bold adaptation by Jessica Kubzansky titled "RII." In this production, Shakespeare's own language is used, but the cast is whittled down to three actors and the action and power of its themes distilled into a powerful live-theater experience. This is a preview performance to be held in advance of Opening Night July 25 at the Grove at Delaveaga Park.
