Pharrell Williams brought along a special guest when he performed at Power 106's annual "Cali Christmas" concert over the weekend. The singer/producer welcomed Kendrick Lamar during his set for the first live performance of their collaboration "Alright".

Taking the stage at The Forum in Inglewood, Los Angeles, Kendrick did most of the rap and teamed up with Pharrell for the hook of the "To Pimp a Butterfly" single which the coach of "The Voice" co-produced with Sounwave.

Following their performance, Skateboard P took to Twitter to thank K. Dot. He shared a photo of them on the stage and captioned it, "WEGONBEALRIGHT @kendricklamar Thank you Inglewood and @Power106LA #CaliChristmas."
