Air (the English translation of the operatic "aria") is the substance of this breath, which informs a rich spiritual history across many cultures and practices. The opera is animated and performed by the rising and falling of loaves of bread dough. The loaves expand and deflate like lungs. Tiny civilizations of yeast performers rise and fall as this movement is enacted. Their process of fermentation becomes a form of collective transformation. The fleshy dough encounters a series of obstacles to its progress and finds various ways to overcome these restraints as it reaches beyond itself. Inspired by Baroque opera staging, Victorian monodrama, and contemporary design, Air (an opera for breath) explores the corporeal body through the air that passes through it.
