So I'm a big Neptunes/Pharrell fan, and as a big fan I'm embarrassed I have to ask this, but I was wondering if any of you more aware fans could answer this question for me? I've noticed every once in a while, that certain songs will be produced by Chad Hugo, or produced by Pharrell. Do they no longer work as Neptunes, and only as solo producers, is there a riff, or is this just something that has been going on the last few years? I thought I remember hearing that Pharrell did Hell Hath No Fury on his own, but I can't remember for sure. If anyone can give me a concrete response I'd appreciate it.
