Sometimes the small pleasures are the most intense. Circle Mirror Transformation followed the encounters of a group of small-town, would-be thespians learning acting and performing theater exercises — tell an anecdote, mirror another person vocally and physically, hold a conversation using only nonsense words — and slowly coming to know each other. There were no great revelations or climactic events in this Curious Theatre Company production, just occasional bright moments of insight. The interactions among director Chris Leo's excellent cast were emotionally honest and perfectly timed, and the evening was pure pleasure.
