@allmusic : Innovative funkster Roger Troutman was the master of the talk box — an effects unit that created robotic-sounding vocals through the simultaneous use of a piano-like interface and a breath controller (breath tube).
@last.fm : As a member of Zapp, a band that included his brothers Larry, Lester, and Terry, and recording under the solo moniker of Roger, he helped define and give life to a difficult-to-play instrument that previously was used for gimmicky effects and, as played by others, was basically devoid of personality.
