Musical: Oklahoma!
Play: The Inheritance and The Sound Inside
Immersive: The Blood Comedies and The Winter Machine (both in L.A.). The Blood Comedies is my favorite theatrical experience of any kind. It was just me and one actor in a room for 30 minutes and it was one of the best things I've ever experienced. By the end of it, I was sobbing, the actor was crying, we were hugging, it was extraordinary.
