Theater up here is pretty moribund, but I heard good reviews of local newsman Dave Silverbrand's /The Lobster War/, an account of some Maine lobstermen's battle against... uh... some government policy or other. Damn, now I'm ashamed that I didn't go see it.
The best play I've ever seen was a student's production of Miguel Angel Asturias' /El Senor Presidente/ in Quetzaltenango, Guatemala. If you don't know the story, it's about a young idealist, a Guatemalan government functionary, who throughout the play comes to understand depth of his government's corruption. (If you've been jazzed up by the play that you saw, I'd recommend a look at /ESP/ or Asturias's /Men of Corn/). It was quite brave of the students to do this production-- this was back when people were still being "disappeared" left and right. (Are they still?)
At one point in the play, the actors snuck down the isles and whispered in peoples' ears: "Viene el Senor Presidente!" It scared the hell out of me. Then the President took the stage-- with a giant ugly puppet-face and a group of hangers-on. Young Miguel Angel (the functionary) was torn between the President's speech and the jeers of his friends, chorus of beggars and indigenous people who watched from the wings.
