 Seeing Sounds is the third studio album by American funk rock band N.E.R.D released June 10 , 2008 on Star Trak Entertainment and Interscope Records in the United States . After ending their contract with Virgin Records in 2005 , the band felt their previous album Fly or Die ( 2004 ) was too consistent . Using their own money , the band recorded the album in Florida and California . The album was produced solely by record production duo The Neptunes , consisting of Pharrell Williams and Chad Hugo , with additional assistance by rock band Spymob and was mainly written by Williams . The album 's title , as well as its content , revolves around the neurological phenomenon of synesthesia , the mixing of sensory modalities .
