Based on your interests, THE COLOR PURPLE should be #1 on your list. Then probably THE LION KING or WICKED. But if you like drama and strong music, add GREY GARDENS to your list.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
