The title suggests that this bluegrass musical version of Sophocles' play is essentially a derogatory joke hinging on the assumption that putting rural mountain folk in a Greek tragedy is like bringing pigs to church. And ultimately the world here doesn't so much resemble Thebes as a lurid Li'l Abner strip: cocreators Rick Sims and Heidi Stillman have comedy in mind and throw in every Appalachian stereotype they can think of--family feuds, religious fanaticism, incest. Yet ultimately the work's unflattering stereotypes and over-the-top cartoon approach come to seem the comedic equivalents of the larger-than-life situations of the tragedy, offering a goofily exaggerated look at some of Sophocles' themes. Stillman's colorful production zips along driven by Sims's lively bluegrass score, played and sung by a chorus of three, among them Sims himself.
