The title of N.E.R.D's third album, 'Seeing Sounds', was inspired by a TV show the band watched about synaesthesia - the neurological disorder that causes people to experience sounds as colours or objects in their minds.
The concept inspired the trio (Pharrell Williams, Chad Hugo, a.k.a. The Neptunes, and their rapping pal Shay Haley) to create a record as if it were a live show, as if the listener were really able to see the band playing.
The album is a blistering mash-up of booming hip-hop beats and rollercoastering rock riffs, rumbling crunk rhythms and scintillating soul music.
Christian Grahn is featured on drums and percussion in the tracks Time For Some Action and Windows. Drums on all other tracks are performed by Eric Fawcett.
