With the Duke Chorale and the Choral Society of Durham, the DMO presented Philip Glass’ “Itaipú” and Eric Whitacre’s “Deep Field.” “Itaipú” sets the text of the creation myth of the Guaraní, an indigenous group of Paraguay and Brazil. “Deep Field,” inspired by images from the Hubble telescope, features a smart-phone app used by the audience as part of the performance.
