Richard Boehler, director of the new production of Julius Caesar currently playing at the Vortex, says: "While I very much feel this piece reflects obviously on American politics and culture, I don't think you have to have people running around in business suits with guns or have the cast wrapped in flags, rapping, for the parallels to come through." Good point. Boehler sets the play in the period Shakespeare intended, but it should be easy to draw connections between the performance in the theater and the political backbiting in the world at large. The show runs Fridays and Saturdays at 8 p.m., $10 general, $8 seniors/students, Sundays at 6 p.m., $7, through Oct. 5. 247-8600.
