In a new commercial for Beats by Dre, Kendrick Lamar spits a new verse in the studio with Dr. Dre manning the soundboard. The beat also appears to be produced by Dre as well. Kendrick stops midway through the verse so he and Dre can have a conversation about the song before they take a break from the recording session. After sitting on it for a day, they both decide that the drums need to be changed and continue with their session. This commercial is to promote the company's new Beats Pill portable speakers. Watch the three-minute clip above.
