N.e.r.d Scrapped 27 Songs Before Finding New Sound

Pharrell Williams scrapped 27 songs before coming up with the right sound for N.E.R.D's latest album - because none of the new material was "good enough".
The group is preparing to release its first album since 2008's Seeing Sounds, and Williams admits the studio process left the band with a mountain of work they didn't want to use.
After dumping a staggering 27 tracks, the hip-hop trio started afresh - and focused on creating a sound tailored specifically for women.
Williams says,"We scrapped 27 records because they weren't good enough, they sounded great - but what were they saying? So we went back in (to the studio) and just focused on feeling. It's almost like we did this whole entire album with our eyes closed, not because it was that easy but because it was that important to reconnect to what we feel and I would say this album is like scrapping everything and starting with nothing.
"The music has been especially tuned in frequencies to speak to women. Women will literally feel this. We are doing some other next level experimentation with this music... and it's the sexiest thing that I could ever give to a woman."
