For more than three decades, Sweet Honey in the Rock has explored the rich heritage of African-American music, including the music of the black church. The a cappella group was founded by Bernice Johnson Reagon in 1973. These days, Sweet Honey still sings gospel and spirituals, along with new songs steeped in African-American history. Sweet Honey recently launched its 36th season with a concert presented by the Duke Gardens and Duke Performances. Longtime member Ysaye Barnwell spoke with Faith & Leadership about the music and the messages that inspire this unique ensemble.
