Power 106’s annual Cali Christmas concert took place last night at The Forum in Inglewood, CA where the night featured a star-studded lineup that included Macklemore, Wiz Khalifa, Ty Dolla $ign, Travis $cott and Post Malone, G-Eaazy, Logic, Dej Loaf and Skeme. Also hitting the stage as the event’s “special guest performer” was Pharrell Williams who stunned the crowd with one of night’s most memorable moments. After wrapping up his set with “Happy,” Pharrell shared a heartfelt speech touching on all the issues across the world as of late. This ended up being the perfect setup for his next surprise, which was none other than Kendrick Lamar. Both performed “Alright” for the first time together and it couldn’t have been a better way to end the night. Watch above.
