With a whole host of traditional plays and musicals available to choose from, it is sometimes refreshing when theater artists in New York City experiment with form. Creator and producer Brett Epstein’s Rule of 7x7 is just that: an experiment in playwriting wherein seven playwrights each declare a “rule” that must be incorporated into each play. These rules range from a word, a line, or a specific stage direction. To intensify the process, the artists involved have just one month to mount these short plays from conception to performance.
