Pharrell Williams has played a crucial role in the progression of post-new jack swing R&B and rap, and consequently pop. Williams actually got his start during the tail-end of the new jack era as the co-writer of Wreckx-N-Effect’s number two 1992 pop hit “Rump Shaker”. After numerous accolades for the Neptunes, including a Grammy for Producer of the Year in 2004 and a Producer of the Decade acknowledgment from Billboard, the charismatic Williams remained a force in mainstream music as a producer, songwriter, tough-talking rapper, and falsetto-equipped singer.
