Kabbage Boy is an incredibly shitty metal band that appears in the intro of Brütal Legend, during one of their concerts where Eddie Riggs is working as the head roadie at the time. After a demon made of chrome is summoned as a result of an accident on stage, the entire band, with the exception of the bassist, who manages to flee into the crowds is killed by the Beast. Despite the attitudes and comments towards Kabbage Boy's music, their song "Girlfriend" is an unlockable track for the Deuce's Mouth of Metal radio later in the game.
- The Mouth of Metal, the Deuce's in-game music system, classifies their genre as S.W.O.A.T.M.R.M. - "Second Wave of American Tween Melodic Rap Metalcore"
- The lead guitarist is voiced by Richard Steven Horvitz, who also voiced Razputin, the protagonist of Double Fine's previous game, Psychonauts. The guitarist also performs Raz's victory dance during the intro of Brütal Legend.
