The circus has come to Broadway and the musical team behind it has been clowning around together since their freshman year at Carnegie Mellon University’s School of Drama. But clowning around is serious work for PigPen Theatre Co(opens in new window). This band of storytellers, made up of seven CMU alumni (Alex Falberg, Arya Shahi, Ben Ferguson, Curtis Gillen, Dan Weschler, Matt Nuernberger, and Ryan Melia) has created and produced imaginative musical works that have been performed all over the world. Now, the group is making their Broadway debut as the composers and lyricists of “Water for Elephants(opens in new window),” which opened on March 21 at the Imperial Theatre in New York.
