Dr. Dre's Detox may be a rap fan's pipe dream, but that doesn't mean the good doctor isn't working on any music.

On August 14, N.W.A.'s much-anticipated biopic "Straight Outta Compton" will be hitting theaters and guess who's handling the movie's soundtrack?

"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," the film's director, F. Gary Gray, told MTV News on Friday (July 10) during an interview at San Diego Comic-Con, where he was promoting a new short based on the video game "Assassin's Creed."

Gray says he's been blasting the film's soundtrack at home and has been excited about the overall musical direction and two of the rappers that Dre pulled for the project. "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," revealed Gray, who was at SDCC to promote his animated short, "Assassin's Creed Syndicate." "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."

For hip-hop fans who feel they know all there is to know about the iconic rap group, Gray promises a deeper look into gangsta rap pioneers. That's the benefit of working with N.W.A. members Dr. Dre and Ice Cube.

"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."

Yup, that's exactly what we want to see.
