In August: Osage County, Tracy Letts describes the Great Plains as a state of mind--"some spiritual affliction, like the Blues." That sense of heartland ennui suffuses Brian Golden's new one-act, set in rural Nebraska. Jean and her brother, Boxer, grew up there. Boxer, a trumpeter, got out as soon as he could; Jean stayed, had a couple kids, languished. They've reunited for the funeral of their mother, a onetime beauty queen and lifelong ice princess. Golden's natural, unadorned dialogue mirrors the flatness of the landscape but also supplies undercurrents of longing and regret. Not a moment feels false in this New Leaf Theatre production thanks to Marsha Harman and Ted Evans, who, as the siblings, capture the bittersweet blend of love and resentment unique to the familial bond. --Zac Thompson
