The surprise? A mobile concert on the back of a moving truck, in collaboration with Reebok’s #GetPumped campaign. The trucked rolled down Sunset Boulevard and Melrose in West Hollywood as K Dot performed new music off of his album To Pimp A Butterfly and Goodkid MAAD City classics as well. Thousands of Kendrick fans ran for about 5k behind the tractor-trailer truck with an attached flatbed while Kendrick performed on top of the stage getting fans fit with a dose of hip-hop on wheels.
