Hi Matt- 2 years ago I had the distinct pleasure of producing our high school's musical of AIDA. We are from a very rural area with limited diversity. We chose the show for it's themes and music, not because of the ethnic background. The production was simply amazing. The emotion our High Schoolers gave to the production was incredible. I completely agree with Courtney that the difference in costumes. This is a must. Status is also a big one, work on posture and walking with the actors. The show does not depend on a multi-cultural cast.
