Pulitzer laureate Lewis Spratlan's imaginative Hesperus is Phosphorus was commissioned and performed here by The Crossing and Network for New Music. Building a libretto with texts ranging from Adrienne Rich and Richard Feynman to David Eagleman and the Magnificat, Lewis offers a re-examination of our perceptions and the discoveries found in rethinking them from a wider perspective.

Referred to by The Philadelphia Inquirer's David Patrick Stearns as "a composition tour-de-force," this hour-long, nine-movement work for mixed chorus and chamber ensemble is a sonic bath, at times truly hysterical, at others deeply moving.
