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.
