When it comes to imagination and involvement, Cleveland Public Theatre is in a league all its own. They staged the fascinating and fast-paced Wanderlust, and their version of Open Mind Firmament provided a new take on Irish poet W.B. Yeats. Topping off these bold forays, CPT also works with the homeless, and separately with local teens, to develop theater projects. CPT is always restless, inquisitive, and fearless — and that makes for exciting theater.
