This summer’s program, “Voices of Earth,” invites singers into a season of music shaped by wonder, mystery, humor, and the beauty of the world around us, exploring how nature, place, and human experience give voice to the earth. Featuring music by composers such as Thomas Morley, Ēriks Ešenvalds, Eric Whitacre, Johannes Brahms, Dan Forrest, Mark Sirett, and others, the season offers a rich and varied musical journey full of color, contrast, and expressive depth.
