The N.W.A. biopic Straight Outta Compton, which includes Ice Cube and Dr. Dre as producers, is coming out next month. As MTV reports, Dre is also curating the soundtrack, which includes Kendrick Lamar, Eminem, and new material by Dre himself. “Dr. Dre, it took him 15 years to step out and say, ‘I want to do music again’ in the way that he’s doing it,” director F. Gary Grew told MTV News at San Diego Comic-Con. “The soundtrack is insane. Seriously, it’s incredible. He went deep and you can hear some of his influences, with jazz and soul and a little bit of funk. And Kendrick Lamar is on, Eminem; a lot of great guest stars. But it’s really Dre and how he’s evolved and how he’s matured as not only a person, but as an artist. It’s deep and it’s great.” Watch the full interview below.
