Breath Control: The History of the Human Beat Box (2002) is a documentary exploring the world of beatboxing, a form of music using the human mouth, throat and diaphragm to generate sounds that are usually produced by machines. Over 30 practitioners of this art form discuss their techniques and the evolution of their craft. The human beat box is one of the key elements in the development of Hip Hop culture, alongside Dj-ing, Graffiti, Breakdancing, and MC-ing. Unfortunately, its contribution has been largely overlooked, as has the fun, expressive, human, and spontaneous dimension of Hip Hop that it represents. As the first documentary of its kind, Breath Control: The History of the Human Beat Box uses interview's, live performances, archival footage, and animation to bring to light this important and neglected ingredient of Hip Hop's identity .
