This is Dr. Martin Luther King Jr.'s "symphony of social justice"

In 1963, Dr. Martin Luther King Jr. wrote his iconic "Letter from the Birmingham Jail," a profoundly important message that King's adviser and friend Dr. Clarence B. Jones called a "symphony of social justice." In 2018, Oakland composer Zachary Watkins (Black Spirituals) wrote Peace Be Till for the contemporary classical group Kronos Quartet, in honor of Dr. King's activism. The staggering excerpt above features Dr. Jones, currently director of the University of San Francisco Institute for Nonviolence and Social Justice, reads from the "Letter from the Birmingham Jail."

Peace Be Till premiered on January 19, 2018, at New York City's Carnegie Hall during "The '60s: The Years that Changed America" festival.
