Zapp is an American funk band that emerged from Dayton, Ohio, United States, 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—first cousin, Sherman Fleetwood—and non-Troutman family members Bobby Glover, Gregory Jackson, Jerome Derrickson, Eddie Barber, Jannetta Boyce and Shirley Murdock. 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.

Funk is a music genre that originated in African-American communities in the mid-1960s when musicians created a rhythmic, danceable new form of music through a mixture of various music genres that were popular among African-Americans in the mid-20th century. It deemphasizes melody and chord progressions and focuses on a strong rhythmic groove of a bassline played by an electric bassist and a drum part played by a percussionist, often at slower tempos than other popular music. Funk typically consists of a complex percussive groove with rhythm instruments playing interlocking grooves that create a "hypnotic" and "danceable" feel. It uses the same richly colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, and dominant seventh chords with altered ninths and thirteenths.
