Mac Miller is about to drop a music video for "Diablo," the lead single and standout track off his last mixtape, Faces. Last night he dropped a three-minute long "teaser," with the promise of a "full video" to come. The video finds Mac surrounded by his crew in the streets of Los Angeles, a cigarette and bouquet of flowers in hand. A truck promoting "Old Jewish," Mac's website, sits in the backdrop. "Diablo" is now available on iTunes here. Mac has only dropped one project this year, despite promising four before the year's end. However, he's remained busy by working on his television show and producing for artists such as Your Old Droog.
