N*E*R*D's critically acclaimed third album, Seeing Sounds, is conceptually based on the neurological phenomenon of synesthesia—the mixing of sensory modalities—for instance, seeing colors when listening to music. The album's instantly recognizable cover art, with the large looming gorilla and classic N.E.R.D font, was a return to form for the group after leaving their previous label. The duo of Pharrell Williams and Chad Hugo—also otherwise known as The Neptunes—expanded their top-tier production by exploring atmospheric rock tangents with more added emotional appeal than previous, more straightforward efforts. It has been reissued on 2LP standard black vinyl and features two bonus tracks—"Lazer Gun" and "Everyone Nose (All The Girls Standing In Line For The Bathroom)" remix featuring Kanye West, Lupe Fiasco, and Pusha T—on vinyl for the first time.
