"King Tim III (Personality Jock)" is a 1979 hip hop song by the Fatback Band from the disco album Fatback XII. Engineered by Delano “Rock” McLaurin and released on March 25, 1979, this song is often cited as the beginning of recorded hip hop music. The title refers to vocalist Tim Washington. A few months later, "Rapper's Delight" came out, which is widely regarded as the first commercially released hip hop song.
