On our audio diary series “The Big Break,” understudies and apprentices take us behind the curtain at the Kentucky Opera, Actors Theatre of Louisville and the Louisville Ballet. The season is almost over for the actors and dancers. Her time in Louisville is almost up, so Actors Theater apprentice Samantha Beach has to decide where she wants to build the next phase of her career. Louisville Ballet trainee Claire Horrocks makes plans for her summer that will help her prepare for a possibility every dancer fears -- the day she can't dance anymore.
