Pharrell headlined Odd Future’s annual Camp Flog Gnaw Carnival in Los Angeles over the weekend, and a couple notable things happened during his set. For one, his N.E.R.D. cohorts Chad Hugo and Shay Haley joined him on stage for a brief reunion performance that brought Tyler, The Creator to tears.

Pharrell also debuted a new Gwen Stefani song called “Spark The Fire” off his phone, saying “it’s about feminism.”

Our photographer Jasper Bernbaum was on the scene. He notes that the mood was mellow, especially by Odd Future standards. Pharrell streamed some more songs off his phone including Clipse’s “Mr. Me Too” with Tyler rapping over it live. Freddie Gibbs gave a great performance, Mac Miller brought out Schoolboy Q as a surprise guest, Diplo played a surprise DJ set, and Action Bronson left the stage for a 15-minute food break before returning for one last song. Bernbaum also reports that Tyler had the best set design (involving oversized furniture) and gave “a super genuine performance.” Scroll through his photos above.
