On a hot, sticky. busy, loud, crowded afternoon in Uptown (which is quickly becoming my least favorite neighborhood in which to see theater due to the never-ending traffic, construction, and parking difficulties), I found a cool, sweet, pleasing oasis in the SpringHouse Ministry Center. Theatre Coup D'Etat's production of the one-act 1990 Off-Broadway play The Baltimore Waltz is a funny, charming, poignant little waltz of a play. Playwright Paula Vogel wrote the play in response to her brother's death, and that sense of nostalgia, grief, and the ephemeral joy of life permeates every scene. The appealing three-person cast in the intimate setting sweep the audience up with them in this fantastical journey of the imagination.
