Calibretto 13 was an acoustic punk band from Kokomo, Indiana, United States. The band existed in three incarnations. The first being Black Sheep, then Calibretto 13, and finally Calibretto. Calibretto 13 was inspired by a comic book, and 13 was the only number that they all liked. Later, they shortened it to just Calibretto. The acoustic punk style of the band and the peculiar vocal style of singer Joe Whiteford gives the band their signature sound.
