Zapp (also known as the Zapp Band or Zapp & Roger) is an American funk band that emerged from Dayton, Ohio, in 1977. Particularly influential in the electro subgenre of funk, Zapp were known for their trademark use of the talk-box effect. Zapp released its eponymous debut album in 1980, and achieved mainstream recognition from the single "More Bounce to the Ounce". The group's follow-up Zapp II was released in 1982, selling well and becoming certified gold. In the 1990s, Zapp would also be an influence on the regional G-funk sound and the broader cultural scene of West Coast hip-hop itself. Zapp reformed briefly in 2003 with the remaining brothers of the Troutman family to produce the album Zapp VI: Back By Popular Demand.
