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.The original line-up consisted of four Troutman brothers—frontman Roger, Larry, Lester and Terry—and non-Troutman family members Bobby Glover, Gregory Jackson, Sherman Fleetwood, Jerome Derrickson, Eddie Barber and Jannetta Boyce.Zapp also worked closely with George Clinton and Bootsy Collins of 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, 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 G-funk sound of popular in West Coast hip-hop.The band disbanded in 1999 after the deaths of Roger and Larry Troutman in a murder-suicide apparently carried out by Larry.Zapp reformed briefly in 2003 with the remaining brothers of the Troutman family to produce the album Zapp VI: Back By Popular Demand.
