Roger Troutman (November 29, 1951 – April 25, 1999), also known simply as Roger, was an American singer, composer, songwriter, producer, multi-instrumentalist and the founder of the band Zapp who helped spearhead the funk movement and heavily influenced West Coast hip hop due to the scene's heavy sampling of his music over the years. Troutman was well known for his use of the talk box, a device that is connected to an instrument (frequently a keyboard, but most commonly a guitar) to create different vocal effects.
