Dre’s first new music in aeons sounds “insane”, says director.

Straight Outta Compton, the forthcoming NWA biopic, will feature new music from Dr. Dre, Eminem and Kendrick Lamar.

“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. The soundtrack is insane. Seriously, it’s incredible,” F. Gary Gray told MTV News.

“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,” he said in an interview at San Diego Comic-Con, where he was promoting a new short based on video game Assassin’s Creed. “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.”

Gray also talked about the benefits of working with the original NWA members. “The details, the stories, the authenticity that you get and you can draw from these guys, it goes beyond googling what happened in the Death Row days or googling what happened when the group broke up,” he said. “And I think that’s what people want to see.”
