The Blue Hour features Grammy-winning singer Luciana Souza in a song cycle written by a collaborative of five leading composers – Rachel Grimes, Angélica Negrón, Shara Nova, Caroline Shaw, and Sarah Kirkland Snider. The text that serves as the libretto is by 2017 Windham-Campbell Prize winner Carolyn Forché. The excerpted poem, “On Earth,” is from Forché’s 2003 collection Blue Hour. The remarkable poem takes the form of an abecedarium: a listing of images, thousands of them, in alphabetical order, like a flurry of memories from a life coming to its end.
