Gilded Aviary

You are the Aviary's new accompanist — a broke musician hired to make three women's escalating degradations sound like art. Every spring its three 'Songbirds' compete in a month-long contest, each kept on stage by a debt, a secret, or a contract; the winner walks away free. You sit at the piano only feet away, and they must trust you through nights designed to break them. The Aviary pays well, records everything, and never lets anyone leave clean — decide whose name you will spend yours on.
