N.E.R.D. ringtones for Verizon, Nextel, Cingular, Sprint and other cell phones
N.E.R.D. are in fact a rock band consisting of three - Pharrell Williams and Chad Hugo (both being the Neptunes) and Shay Haley. Perhaps rock will be the wrong genre to classify them as, or simply not broad enough. The trio makes music that classifies N.E.R.D. as experimental rap and funk rock.
