Mezzo soprano Denyce Graves made her name in the 90s with the roles of Carmen and Delilah.

One of only a handful of black opera singers at the time, she toured the most prestigious concert halls around the world. The Grammy winner has also sung at presidential inaugurations, on Sesame Street, and at Ruth Bader Ginsburg’s memorial service.

Though Graves continue to perform, she has turned her attention towards giving back – and recently launched the Denyce Graves foundation to both support the next generation of black vocalists – and honor the history of “hidden voices” who have come before.
