I learned a lot. Glass shows the importance of the various roles such as director, producer, scenic designer, composer, libretist, funder, etc, etc. I learned the complexity of the decisions needed to bring a new production to fruition. What was most suprising was the acceptance or even interest in seeing different takes that different directors bring to productions of the same work. Glass clearly has a deep appreciation of the scenic impact and what will have a dramatic impact on an audience. He closely considers the language to be used for each audience. The book centers on his three major operas, Einstein on the Beach, Satyagraha and Akhnaten but also provides insights into lots of other Glass pieces and collaborations. ( )
