Zapp (also known as the Zapp Band or Zapp & Roger) is an American funk band that emerged from Hamilton, Ohio, in 1977. Particularly influential in the electro subgenre of funk, Zapp served as partial inspiration toward the creation of the G-funk sound of hip-hop popular on the West Coast of the United States in the early to mid 1990s, with many of their songs sampled by numerous hip-hop artists. The original line-up consisted of four brothers—Roger Troutman, Larry Troutman, Lester Troutman and Terry Troutman—and non-Troutman family members Bobby Glover and Gregory Jackson. The group received attention in the early 1980s for implementing heavy use of the talk-box, which became one of their most well known characteristics. Zapp worked closely with members George Clinton and Bootsy Collins of the band Parliament-Funkadelic during its early stages, their support being a factor in the group gaining a record deal with Warner Bros. Records in 1979. Zapp released its eponymous debut album in 1980, having a P-funk reminiscent sound as a result of Clinton's and Collin's input on the production. Zapp achieved most of its mainstream recognition from the single "More Bounce to the Ounce" from the same album, now widely regarded as a classic example of early 1980s electronic funk. The following year in 1981, Clinton stopped producing the band over a record dispute regarding Roger Troutman's solo debut. Zapp continued to produce several more albums thereafter, releasing Zapp II in 1982. The album's musical style veered drastically away from their first release; despite this, the album sold well, and was certified gold by late 1982.
