Sweet Honey in the Rock are an all-female, African-American a cappella ensemble that started in 1973. They are a three-time Grammy Award–nominated troupe who express their history as black women through song, dance, and sign language. Originally a four-person ensemble, the group has expanded to five-part harmonies, with a sixth member acting as a sign-language interpreter. Although the members have changed over five decades, the group continues to sing and perform worldwide.
