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