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.
