Sister Lena Mae Perry says music is like medicine. She would know. At 80-years-old, Sister Perry has helmed the Branchettes, a celebrated gospel group from Johnston County, North Carolina, for decades. To see her perform is to witness the healing powers of music, and, at risk of cliché, to be taken to church. Born in Johnston County in 1940, she grew up in a farming family that deeply valued education, faith, and music.
