Joe Louis Walker (born December 25, 1949 in San Francisco, California) is an American blues guitarist, singer and producer. Walker's parents were blues fans, and introduced him to the music when he was young.
He learned to play the guitar at age fourteen, and left home at sixteen to work as a performer. He soon met Mike Bloomfield, who introduced him to the Bay Area Blues scene. During the 1960s, Walker opened for such artists as Earl Hooker, Freddie King and Lowell Fulson.
