The Neptunes are an American production duo, composed of Pharrell Williams and Chad Hugo, who are credited with contributing the sound for many successful hip hop, R&B and pop artists in the late-1990s and 2000s. The Neptunes' sound is a distinctive brand of off-kilter, stripped-down electronic funk with sounds from Middle Eastern and Asian music including percussion and woodwind. Pharrell sings and (later) raps on records and appears in videos, unlike his production partner Chad, who tends to stay behind the scenes.
