Following a trip to Ghana’s Cape Coast Castle, composer Joyce Solomon Moorman wrote a symphony in two parts. The first marks the arrival of enslaved people to the castle’s famed “door of no return,” and the second represents ancestors coming back centuries later through the “door of return.” The Afro-American Chamber Music Society performed it ahead of Juneteenth at the Grant AME Church in Crenshaw, and Moorman talks to KCRW about her inspiration.
