James "Boo Boo" Davis (born November 4, 1943) is an American electric blues musician. Davis is one of the few remaining blues musicians who gained experience singing the blues in the Mississippi Delta, having sung to help pass the time while picking the cotton fields.
Davis was born in Drew, Mississippi, where he was raised in the heart of Mississippi Delta. Davis's passion for music started at age five when his mother took him to church and he played the harmonica and sang. When he was eighteen years old he began playing drums for the family band, Lard Can Band, because Davis did not possess a drum kit and was forced to play on a lard can. The band featured his multi-instrumental father, Sylvester Sr., his younger brother Sylvester Jr. on the guitar, and his sister Clara on vocals. The band played throughout the state of Mississippi, including a stint as the back up for B.B King, who was unknown at the time.
