Fattburger is a jazz group, best categorized in the jazz-funk, contemporary jazz, or jazz fusion subgenres. The band was formed by saxophonist Hollis Gentry, keyboardist Carl Evans Jr., bassist Mark Hunter, drummer Kevin Koch, and guitarist Steve Laury in San Diego during the early 1980s. Tommy Aros soon joined as a percussionist.

After their first album, Hollis Gentry left the band to launch his solo career (but came back as a part-time member in the 1990s) and after the release of Come & Get It, Steve Laury also left to embark on a solo career. As a result, their next album, "On A Roll," was the first recording of Fattburger as a four-piece band (although Kiko Cibrian and Mark Shapiro (Evan Marks pseudonym) appeared as studio guitarists). Evan Marks joined the band as a permanent member in 1995. After their latest album, Work to Do (2004), Hollis Gentry died on 5 September 2006 and Carl Evans Jr. died on 10 April 2008.
