In Anastasia Traina's acid comedy of family dynamics, at Studio Dante, a mousy twenty-three-year-old downtown artist named Rosie (Bess Rous) gets trapped in a car with her three volatile Italian-American aunts from the Bronx. Crude, loudmouthed Stella (played with wicked timing by Sharon Angela) drives and stirs the pot, while tenderhearted Fannie (Catherine Curtin) labors to keep the peace and self-absorbed Louise (Angelica Torn) contemplates their grim destination: her son's prison. Under Nick Sandow's direction, the ensemble creates a startling picture of the sisters' ancient rivalries and unmet longings, sustaining a note of prickly tension under the laughs. A late, unconvincing plot twist asserts that the sisters' bite is worse than their bark, but it's that bark-painful, childish, and oh so familiar-that really persuades.
