Calibretto 13 (later, simply Calibretto) was a Christian folk punk band from Kokomo, Indiana, United States. The acoustic punk style of the band and the peculiar vocal style of singer Joe Whiteford gives the band their signature sound. Another signature mark of the band is themes in their lyrics, which often are about B-movies and problems in pop culture and Christianity. The band also incorporates a bit of influence from folk music.

The trio of Joseph Whiteford (guitar and vocals), Aaron Richardson (bass) and Christopher Thomas (drums) came together in 1998 and released Sibling Rivalry, a split album with No More Droids, in 1999. In 2000 the band put out Enter the Danger Brigade with Tooth and Nail Records. After the band's initial recording sessions for the album, Tooth & Nail thought that some of the submitted songs were too questionable in content and asked the band to reconvene with producer Barry Poynter and record several more. In all, Calibretto 13 recorded 19 songs for Enter the Danger Brigade, and only 11 songs were included on the debut album. Seven of the remaining songs were released as an EP titled From the Secret Files of the Danger Brigade (2000). In the liner notes for From the Secret Files..., Chris Thomas wrote: "[the songs] were kept from being on the album for one reason or another, and because we consider some of these to be our best songs we tried to make sure that you got to hear them. Of course, some of these songs are pretty crappy, too." Calibretto 13 released a second full length album on Tooth & Nail titled Adventures in Tokyo in 2002. This was the band's final release on Tooth & Nail. After the release of Adventures in Tokyo, the band made several changes.
