Bob James
When Andre 3000 once bragged about how he "steady moved them keys like Bob James" people might have been confused as to who this Bob James was. Was he a kingpin? A legend in the game? In a way, yes: Bob James, one of Quincy Jones' proteges, is in fact a kingpin of the keyboard, and a legend in the realm of jazz-funk, whose songs have become the foundation for too many hip-hop classics. Oh, and he also created the theme song to the TV show Taxi, which is legend status enough on its own.
