“Someone asked me this a while ago, what inspires me, and I always say, ‘that which is missing.’” Pharrell Williams said those words in response to a question from New York Magazine‘s Nitsuh Abebe back in a June during an interview centered on the producer/songwriter/rapper/fashion designer’s recent emergence as 2013′s summer It Man-Boy. “That which is missing.” It’s a very Pharrell phrase: koan-like, evocative, mysterious and frustrating. With the Pharrell-featuring “Get Lucky” and “Blurred Lines” doing battle for song of the summer status, the Pharrell-soundtrackedDespicable Me 2 ruling the box office and the Pharrell-produced 2 Chainz track “Feds Watching” creeping up the rap charts, it’s obvious that Skateboard P is dominating the summer. But what’s harder to discern is, to be frank, why now? Why this moment? What was missing?
