Stevie Williams drops knowledge in Beats by Dre’s latest commercial. Beats’ foray into skateboarding came through its partnership with SLS. As a result, it’s produced several commercials featuring skaters over the past couple of years. Its latest is narrated by Stevie Williams and features Leticia Bufoni, Sean Malto, Curren Caples, and Louie Lopez. While it doesn’t get more corporate than Jimmy Iovine, Dr. Dre, and Apple, the message in Beats’ latest ad is as authentic as it gets.
