Which American production duo consisting of Pharrell Williams and Chad Hugo also produced the LL Cool J's unsuccessful tenth album "10"?
The Neptunes 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 and R&B 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.
Castle Walls "Castle Walls" is a song by American singers T.I. and Christina Aguilera, from T.I.'s seventh studio album "No Mercy" (2010). Alex da Kid produced the song and co-wrote it along with Skylar Grey and T.I. The song was initially produced for Diddy's album "Last Train to Paris", but Diddy felt that "Castle Walls" would be better suited to T.I.; Aguilera was later chosen as the featured artist on the song. A hip hop and electro number, "Castle Walls" received mixed response from music critics, some of whom picked it as a highlight from "No Mercy", and some others criticized the song's lyrics. Despite not being released as a single, the track still managed to appear on record charts of several nations, including on the US Bubbling Under Hot 100 Singles, where it peaked at number five.
