Zapp (also known as the Zapp Band or Zapp and Roger) was a soul and funk band formed in 1978 by brothers Roger Troutman, Larry Troutman, Lester Troutman, Tony Troutman and Terry "Zapp" Troutman. Known for hits such as "More Bounce to the Ounce", "Dance Floor" and "Computer Love", the group was a partial source of inspiration to West Coast hip-hop and G-funk, which came out of the hand clapped-drum beat styled funk of Zapp's records with Roger's impressive use of the talk box becoming another reason for the group's impact and its success.
The nucleus of Zapp circled around three of the five Troutman brothers: Lester, Larry and their younger brother Roger. The duo of Lester and Roger started several groups including Little Roger and the Vels. Larry and Tony eventually joined their brothers when their name became Roger and the Human Body, which also included youngest brother Terry.
